## Abstract

A saddle-riding-type vehicle canister arrangement structure is a canister arrangement structure of a saddle riding type vehicle, including: an engine that includes a crankcase; an exhaust pipe that extends downward at a frontward position of the crankcase from a front part of the engine and then passes below the engine; and a canister that recovers an evaporated fuel which is generated at a fuel tank, wherein the canister is arranged between the engine and the exhaust pipe at a frontward position of the crankcase.

## Claims

### Claim 1

A saddle-riding-type vehicle canister arrangement structure which is a canister arrangement structure of a saddle riding type vehicle, comprising:
an engine that comprises a crankcase;
an exhaust pipe that extends downward at a frontward position of the crankcase from a front part of the engine and then passes below the engine;
a canister that recovers an evaporated fuel which is generated at a fuel tank;
a fender that covers a front wheel from an upside; and
a protection member that protects the canister,
wherein:
the canister is arranged between the engine and the exhaust pipe at a frontward position of the crankcase,
the engine further comprises a cylinder that protrudes upward from the crankcase,
at least part of the canister is positioned at a space in a vertical direction between a lower end of the fender and a lower end of the cylinder, and
the protection member comprises a slant part that is slanted such that a more rearward side is located at a higher position.

### Claim 2 (depends on 1)

The saddle-riding-type vehicle canister arrangement structure according to claim 1, further comprising:
a pair of right and left downward tubes that extend downward from a head pipe, wherein the exhaust pipe extends to a frontward position of the pair of right and left downward tubes from the front part of the engine and is then bent to extend downward, and
the canister is arranged at a space in a vehicle width direction between the pair of right and left downward tubes.

### Claim 3 (depends on 1)

### Claim 4 (depends on 1)

The saddle-riding-type vehicle canister arrangement structure according to claim 1, wherein the canister is arranged at a position that is overlapped with a vehicle body right-to-left center line in a front view.

### Claim 5 (depends on 1)

The saddle-riding-type vehicle canister arrangement structure according to claim 1, further comprising:
a protection member that protects the canister.

### Claim 6 (depends on 1)

The saddle-riding-type vehicle canister arrangement structure according to claim 1, further comprising:
an oil cooler that is located at a frontward position of the cylinder, wherein an opening part that is directed to a lower position of the oil cooler and that is directed to an upper part of the canister, is provided on the fender.
