Abstract

A motorcycle comprises a vehicle body frame including a head pipe part, a pair of right and left main frame parts extending rearward from the head pipe part while being inclined in a downward direction, a down frame part extending downward from the head pipe part to a location that is below the main frame parts, and a bridge frame part coupling the main frame parts to the down frame part; a fuel tank supported by the main frame parts; and a canister connected to the fuel tank via an inlet tube and configured to store therein evaporated fuel generated in the fuel tank. The canister is disposed on a first side in a vehicle width direction. In a side view, the canister is disposed in a region surrounded by the main frame part, the down frame part, and the bridge frame part.

First claim

What is claimed is:

1. A motorcycle comprising:
a vehicle body frame including a head pipe part, a pair of right and left main frame parts extending rearward from the head pipe part while being inclined in a downward direction, a down frame part extending downward from the head pipe part to a location that is below the pair of right and left main frame parts, and a bridge frame part coupling one of the pair of right and left main frame parts to the down frame part;
a fuel tank supported by the pair of right and left main frame parts; and
a canister connected to the fuel tank via an inlet tube and configured to store therein evaporated fuel generated in the fuel tank,
wherein the canister is disposed on a first side in a vehicle width direction, with respect to a vehicle body center line extending in a forward and rearward direction, and
wherein in a side view and a front view, at least a portion of the canister is disposed in a region surrounded by the one of the pair of right and left main frame parts, the down frame part, and the bridge frame part.

2. The motorcycle according to claim 1 ,
wherein in the side view, the canister is disposed to extend along the one of the pair of right and left main frame parts.

3. The motorcycle according to claim 1 ,
wherein in the front view, the canister is exposed so that the canister is seen from a front.

4. The motorcycle according to claim 1 , further comprising:
an air-cooled engine disposed below the fuel tank,
wherein the canister is entirely disposed above and forward of an upper end of the air-cooled engine.

5. The motorcycle according to claim 1 , further comprising:
a front fender disposed above a front wheel,
wherein the canister is disposed above a rear edge of the front fender.

6. The motorcycle according to claim 1 , further comprising:
a shroud covering the canister from an outer side in the vehicle width direction.

7. The motorcycle according to claim 1 , wherein when viewed from above, the canister is disposed to partially overlap with one of the right and left main frame parts.

8. A motorcycle comprising:
a vehicle body frame including a head pipe part, a pair of right and left main frame parts extending rearward from the head pipe part while being inclined in a downward direction, a down frame part extending downward from the head pipe part to a location that is below the pair of right and left main frame parts, and a bridge frame part coupling one of the pair of right and left main frame parts to the down frame part;
a fuel tank supported by the pair of right and left main frame parts;
a canister connected to the fuel tank via an inlet tube and configured to store therein evaporated fuel generated in the fuel tank; and
a drain tube connected to a rear end portion of the canister,
wherein the canister is disposed on a first side in a vehicle width direction, with respect to a vehicle body center line extending in a forward and rearward direction,
wherein in a side view, the canister is disposed in a region surrounded by the one of the pair of right and left main frame parts, the down frame part, and the bridge frame part, and
wherein in a top plan view, the canister crosses the one of the pair of right and left main frame parts so that a rear end portion of the canister is directed inward in the vehicle width direction.

9. The motorcycle according to claim 8 ,
wherein the inlet tube extends inward in the vehicle width direction, from a front end portion of the canister.

10. A motorcycle comprising:
a vehicle body frame including a head pipe part, a pair of right and left main frame parts extending rearward from the head pipe part while being inclined in a downward direction, a down frame part extending downward from the head pipe part to a location that is below the pair of right and left main frame parts, and a bridge frame part coupling one of the pair of right and left main frame parts to the down frame part;
a fuel tank supported by the pair of right and left main frame parts; and
a canister connected to the fuel tank via an inlet tube and configured to store therein evaporated fuel generated in the fuel tank,
wherein the canister is disposed on a first side in a vehicle width direction, with respect to a vehicle body center line extending in a forward and rearward direction,
wherein in a side view, the canister is disposed in a region surrounded by the one of the pair of right and left main frame parts, the down frame part, and the bridge frame part,
wherein in a top plan view, the pair of right and left main frame parts include a pair of right and left main frame front parts extending rearward and outward in the vehicle width direction from the head pipe part, and a pair of right and left main frame rear parts extending rearward in the forward and rearward direction from the pair of right and left main frame front parts, respectively, and
wherein in the top plan view, the canister overlaps with one of the pair of right and left main frame front parts.

11. A motorcycle comprising:
a vehicle body frame including a head pipe part, a pair of right and left main frame parts extending rearward from the head pipe part while being inclined in a downward direction, a down frame part extending downward from the head pipe part to a location that is below the pair of right and left main frame parts, and a bridge frame part coupling one of the pair of right and left main frame parts to the down frame part;
a fuel tank supported by the pair of right and left main frame parts; and
a canister connected to the fuel tank via an inlet tube and configured to store therein evaporated fuel generated in the fuel tank,
wherein the canister is disposed on a first side in a vehicle width direction, with respect to a vehicle body center line extending in a forward and rearward direction,
wherein in a side view, the canister is disposed in a region surrounded by the one of the pair of right and left main frame parts, the down frame part, and the bridge frame part, and
wherein in a front view, a center of gravity of the canister is located in the region surrounded by the one of the pair of right and left main frame parts, the down frame part, and the bridge frame part.
