Abstract

An increase in the size of a body portion of a straddled vehicle forward of a steering shaft in a left-right direction and a front-rear direction of a body frame is suppressed to secure a space forward of the steering shaft. Each top end of left optical lens body 35 L and right optical lens body 35 R is located below top edge B 1 of an upper bracket in an up-down direction of the body frame. Each bottom end of left optical lens body 35 L and right optical lens body 35 R is located above bottom edge B 2 of a lower bracket in the up-down direction of the body frame. The left end of left optical lens body 35 L is located on the right of left edge B 3 of a left front-wheel support unit in the left-right direction of the body frame. The right end of left optical lens body 35 L is located on the right of right edge B 5 of the left front-wheel support unit in the left-right direction of the body frame. The left end of right optical lens body 35 R is located on the left of left edge B 4 of a right front-wheel support unit in the left-right direction of the body frame. The right end of right optical lens body 35 R is located on the left of right edge B 6 of the right front-wheel support unit in the left-right direction of the body frame.

First claim

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 left light group that forms a left light distribution that forms at least one of a main beam or a dipped beam, the 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 including a plurality of left highly-directional light units 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 a light distribution forming the left light distribution; and
a right light group forming a right light distribution forming at least one of the main beam and the dipped beam, the 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 including a plurality of right highly-directional light units each having
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 a light distribution 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 left optical lens sections, is disposed below a top edge of the upper bracket 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 edge 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 the right 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,
a right end portion of the left optical lens body is disposed on the right 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,

the left optical lens sections are disposed at positions overlapping each other in the up-down direction of the body frame as viewed from the front of the body frame in the front-rear direction,
the plurality of left highly-directional light units is disposed at positions overlapping each other in the up-down direction of the body frame as viewed from the left of the body frame in the left-right direction,
in the right light group,
a top end portion of a right optical lens body, which is composed of the right optical lens sections, is disposed below the top edge of the upper 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 bottom end portion of the right optical lens body is disposed above the bottom edge 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 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,
a left end portion of the right optical lens body is disposed on the left 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,

the right optical lens sections are disposed at positions overlapping each other in the up-down direction of the body frame as viewed from the front of the body frame in the front-rear direction,
the plurality of right highly-directional light units are disposed at positions overlapping each other in the up-down direction of the body frame as viewed from the right of the body frame in the left-right direction, wherein
a left overlapping portion is an area where neighboring ones of the left optical lens sections, which neighbor each other in the up-down direction, overlap each other in the left-right direction,
a right overlapping portion is an area where neighboring ones of the right optical lens sections, which neighbor each other in the up-down direction, overlap each other in the left-right direction,
the left light group and the right light group are further formed so that a length between the right end portion of the left optical lens body and the left end portion of the right optical lens body in the left-right direction of the body frame is greater than each of
a length of the left overlapping portion in the left-right direction of the body frame, and
a length of the right overlapping portion in the left-right direction of the body frame.

2 . The straddled vehicle according to claim 1 , wherein
each of the left optical lens sections has a left-right direction length in the left-right direction, each of the right optical lens sections has a left-right direction length in the left-right direction, and the left light group and the right light group are formed so that the length between the right end portion of the left optical lens body and the left end portion of the right optical lens body is greater than each of left-right direction lengths of the left optical lens sections and each of the left-right direction lengths of the right optical lens sections.
