Abstract

An increase in the size of a body section of a straddled vehicle forward of a steering shaft in a left-right direction and a front-rear direction of a body frame is limited while a space is secured forward of the steering shaft. In left optical lens body 45 L, top end TE is disposed below bottom edge B 3 of handlebar 23 , bottom end BE is disposed above a bottom end (virtual line Lc) of lower bracket 15 , left end LE is disposed on the right of a right end (virtual line L 6 ) of left grip 24 L, and right end RE is disposed on the left of right edge B 1 of left front-wheel support unit 12 L. In right optical lens body 45 R, top end TE is disposed below bottom edge B 3 of handlebar 23 , bottom end BE is disposed above the bottom end of lower bracket 15 , right end RE is disposed on the left of a left end of right grip 24 R, and left end LE is disposed on the right of left edge B 2 of right front-wheel support unit 12 R.

First claim

The invention claimed is:

1. A straddled vehicle comprising:
a body frame;
a front wheel portion;
a steering shaft turnably supported by the body frame;
an upper bracket having a central portion that is disposed at an upper portion of the steering shaft;
a lower bracket having a central portion that is disposed at a lower portion of the steering shaft;
a left front-wheel support unit disposed on a left of the steering shaft in a left-right direction of the body frame, the left front-wheel support unit connected to the steering shaft to turn integrally with the steering shaft, the left front-wheel support unit including
a left upper member supported by a left portion of the upper bracket and a left portion of the lower bracket, and
a left lower member that supports the front wheel portion and that is displaceable in an up-down direction with respect to the left upper member,

a right front-wheel support unit disposed on a right of the steering shaft in the left-right direction of the body frame, the right front-wheel support unit connected to the steering shaft to turn integrally with the steering shaft, the right front-wheel support unit including
a right upper member supported by a right portion of the upper bracket and a right portion of the lower bracket, and
a right lower member that supports the front wheel portion and that is displaceable in an up-down direction with respect to the right upper member,

a handlebar disposed at an upper part of the steering shaft, the handlebar being configured to turn integrally with the steering shaft and extending in the left-right direction of the body frame;
a left grip disposed at a left portion of the handlebar;
a right grip disposed at a right portion of the handlebar;
a left light group being disposed on the left of the steering shaft in the left-right direction of the body frame, the left light group forming a left light distribution, the left light distribution forming at least one of a main beam and a dipped beam, the left light group including at least one left highly-directional light unit each including
a left light-emitting section that emits highly-directional left light, and
a left optical lens section that refracts the left light to form at least part of the left light distribution; and

a right light group being disposed on the right of the steering shaft in the left-right direction of the body frame, the right light group forming a right light distribution which forms at least one of the main beam and the dipped beam, the right light group including at least one right highly-directional light unit each including
a right light-emitting section that emits highly-directional right light, and
a right optical lens section that refracts the right light to form at least part of the right light distribution,

wherein
in the left light group,
a top end portion of a left optical lens body, which is composed of the at least one left optical lens section, is disposed below a bottom edge of the handlebar in the up-down direction of the body frame as viewed from a front of the body frame in a front-rear direction,
a bottom end portion of the left optical lens body is disposed above a bottom end portion of the lower bracket in the up-down direction of the body frame as viewed from the front of the body frame in the front-rear direction,
a left end portion of the left optical lens body is disposed on a right of a right end portion of the left grip in the left-right direction of the body frame as viewed from the front of the body frame in the front-rear direction,
a right end portion of the left optical lens body is disposed on a left of a right edge of the left front-wheel support unit in the left-right direction of the body frame as viewed from the front of the body frame in the front-rear direction,
at least part of the left optical lens body is disposed on a left of a left edge of the left front-wheel support unit in the left-right direction of the body frame as viewed from the front of the body frame in the front-rear direction,
at least part of the left light group is disposed at a position overlapping with a turn range of the left front-wheel support unit as viewed from the left of the left-right direction of the body frame,

further wherein in the right light group,
a top end portion of a right optical lens body, which is composed of the at least one right optical lens section, is disposed below the bottom edge of the handlebar in the up-down direction of the body frame as viewed from the front of the body frame in the front-rear direction,
a bottom end portion of the right optical lens body is disposed above the bottom end portion of the lower bracket in the up-down direction of the body frame as viewed from the front of the body frame in the front-rear direction,
a right end portion of the right optical lens body is disposed on the left of a left end portion of the right grip in the left-right direction of the body frame as viewed from the front of the body frame in the front-rear direction,
a left end portion of the right optical lens body is disposed on the right of a left edge of the right front-wheel support unit in the left-right direction of the body frame as viewed from the front of the body frame in the front-rear direction,
at least part of the right optical lens body is disposed on a right of a right edge of the right front-wheel support unit in the left-right direction of the body frame as viewed from the front of the body frame in the front-rear direction, and
at least part of the right light group is disposed at a position overlapping with a turn range of the right front-wheel support unit as viewed from the right of the left-right direction of the body frame.

2. The straddled vehicle according to claim 1 , wherein
a maximum lens width of the at least one left optical lens section in the left-right direction is shorter than a length between the left edge of the left front-wheel support unit and the right end portion of the left grip in the left-right direction of the body frame as viewed from the front in the front-rear direction of the body frame, and
a maximum lens width of the at least one right optical lens section in the left-right direction is shorter than a length between the right edge of the right front-wheel support unit and the left end portion of the right grip in the left-right direction of the body frame as viewed from the front in the front-rear direction of the body frame.

3. The straddled vehicle according to claim 1 , wherein
a length between the left end portion of the left optical lens body and the right end portion of the left optical lens body in the left-right direction of the body frame is shorter than a length between the left edge of the left front-wheel support unit and the right end portion of the left grip in the left-right direction of the body frame as viewed from the front in the front-rear direction of the body frame, and
a length between the right end portion of the right optical lens body and the left end portion of the right optical lens body in the left-right direction of the body frame is shorter than a length between the right edge of the right front-wheel support unit and the left end portion of the right grip in the left-right direction of the body frame as viewed from the front in the front-rear direction of the body frame.

4. The straddled vehicle according to claim 1 , wherein, as viewed from the front of the body frame in the front-rear direction, at least part of the left optical lens body is disposed both
