Abstract

A vehicle, including: a body frame; a saddle-style seat provided on the body frame; a pair of front wheels provided at a front portion of the body frame; a pair of rear wheels provided at a rear portion of the body frame; an engine provided in the body frame and including a crank shaft extending in a width direction of the vehicle; and a footrest provided at the body frame and including a first step and a second step provided behind the first step and extending diagonally rearward. The crank shaft is located between an upper end and a lower end of the second step in a height direction of the vehicle, and further rearward than the second step in a fore-aft direction of the vehicle.

First claim

The invention claimed is:

1 . A vehicle comprising:
a body frame; a saddle-style seat provided on the body frame; a pair of front wheels provided at a front portion of the body frame; a pair of rear wheels provided at a rear portion of the body frame; an engine provided in the body frame and including a crank shaft extending in a width direction of the vehicle; and a footrest provided at the body frame and including a first step and a second step provided behind the first step and extending diagonally rearward, wherein the crank shaft is located between an upper end and a lower end of the second step in a height direction of the vehicle, and further rearward than the second step in a fore-aft direction of the vehicle.

2 . The vehicle according to claim 1 , further comprising an engine unit provided in the body frame and including:
the engine, and a continuously variable transmission provided on an outboard side of the engine and having an input shaft for receiving an output from the engine, wherein the input shaft is located between the upper end and the lower end of the second step in the height direction of the vehicle, and further rearward than the second step in the fore-aft direction of the vehicle.

3 . The vehicle according to claim 1 , wherein the engine at least partially overlaps with the rear wheel in a side view of the vehicle.

4 . The vehicle according to claim 1 , further comprising:
a fuel tank for storage of a fuel to be supplied to the engine, and a canister provided between the engine and the fuel tank.

5 . The vehicle according to claim 4 , further comprising an electric box provided above the fuel tank.

6 . The vehicle according to claim 1 , wherein
the engine includes a cylinder head, and the vehicle further comprises a fuel tank provided in front of the engine, a lower end of the fuel tank being lower than a lower end of the cylinder head in the height direction of the vehicle.

7 . The vehicle according to claim 6 , further comprising an electric box provided above the fuel tank.

8 . The vehicle according to claim 1 , wherein
the engine includes a cylinder head, and the vehicle further comprises an air cleaner provided in front of the cylinder head so as to overlap with the engine in a front view of the vehicle.

9 . A vehicle comprising:
a body frame; a saddle-style seat provided on the body frame; a pair of front wheels provided at a front portion of the body frame; a pair of rear wheels provided at a rear portion of the body frame; an engine unit provided in the body frame and including:
an engine, and
a continuously variable transmission provided on an outboard side of the engine and having an input shaft for receiving an output from the engine; and
a footrest provided at the body frame and including a first step and a second step provided behind the first step and extending diagonally rearward, wherein the input shaft is located between an upper end and a lower end of the second step in a height direction of the vehicle, and further rearward than the second step in a fore-aft direction of the vehicle.

10 . The vehicle according to claim 9 , wherein
a first imaginary line and a second imaginary line cross each other at a point of intersection, which overlaps with the continuously variable transmission in a plan view of the vehicle, wherein the first imaginary line is an imaginary line passing through a rear end portion of the second step and extending in a width direction of the vehicle, and the second imaginary line is an imaginary line passing through an inner end portion of the second step and extending in the fore-aft direction of the vehicle.

11 . The vehicle according to claim 9 , wherein the second step overlaps with the continuously variable transmission in a side view.

12 . The vehicle according to claim 9 , further comprising a transmission provided in front of the engine as a separate component from the engine for speed-change of an output from the continuously variable transmission.

13 . The vehicle according to claim 9 , further comprising an intake duct connected with the continuously variable transmission for supplying air to the continuously variable transmission, wherein
the engine including a cylinder block, and the intake duct does not overlap with the cylinder block in a plan view of the vehicle.

14 . The vehicle according to claim 9 , further comprising an intake duct connected with the continuously variable transmission for supplying air to the continuously variable transmission, wherein
the intake duct has an air inlet on a same side as the continuously variable transmission with respect to a centerline of the vehicle in a plan view thereof.

15 . The vehicle according to claim 9 , further comprising an intake duct connected with the continuously variable transmission for supplying air to the continuously variable transmission, wherein
the intake duct has an air inlet at a position more forward than a front end of the saddle-style seat in a plan view of the vehicle.

16 . The vehicle according to claim 9 , further comprising:
an intake duct connected with the continuously variable transmission for supplying air to the continuously variable transmission, and a battery provided in front of the saddle-style seat, wherein the intake duct has an air inlet at a position higher than the battery.

17 . The vehicle according to claim 9 , further comprising:
an exhaust duct connected with the continuously variable transmission for discharging exhaust from the continuously variable transmission, an exhaust pipe connected with the engine for discharging exhaust from the engine, and a muffler connected with the exhaust pipe, wherein the exhaust pipe has:
a first pipe portion connected with the engine,
a second pipe portion connected with the muffler, and
a spherical joint connecting the first pipe portion and the second pipe portion with each other, and
the exhaust duct has an exhaust outlet facing the spherical joint.
