Abstract

A canister structure for a saddle riding vehicle, including a canister connected with a fuel tank using a connection line, the canister adsorbing fuel vapor generated in the fuel tank, and a purge valve disposed in a path through which the fuel vapor is returned from the canister to an air intake system of an engine, includes an annular canister rubber that fits over an outer cylinder of the canister; a canister stay disposed on a vehicle body side; and an engagement portion disposed on the purge valve. In the canister structure, the canister rubber has, formed on an outer periphery thereof, an anterior-side mounting portion and a posterior-side mounting portion each having an insertion hole in which the canister stay is inserted and a purge valve mounting portion having an engagement portion insertion hole in which the engagement portion of the purge valve is inserted.

First claim

The invention claimed is:

1. A canister structure for a saddle riding vehicle, including a canister connected with a fuel tank using a connection line, the canister adsorbing fuel vapor generated in the fuel tank, and a purge valve disposed in a path through which the fuel vapor is returned from the canister to an air intake system of an engine, the canister structure for a saddle riding vehicle, comprising:
an annular canister rubber that fits over an outer cylinder of the canister;
a canister stay disposed on a vehicle body side; and
an engagement portion disposed on the purge valve, wherein
the canister rubber has, formed on an outer periphery thereof, a vehicle body-side mounting portion having an insertion hole in which the canister stay is inserted and a purge valve mounting portion having an engagement portion insertion hole in which the engagement portion of the purge valve is inserted.

2. The canister structure for a saddle riding vehicle according to claim 1 , wherein
the purge valve mounting portion is disposed on an upper portion of the canister rubber and the vehicle body-side mounting portion is disposed on a lower portion of the canister rubber,
the canister stay includes an anterior-side stay portion that extends vertically at a position anterior to the canister and a posterior-side stay portion that extends vertically at a position posterior to the canister, and
the vehicle body-side mounting portion includes an anterior-side mounting portion in which the anterior-side stay portion is inserted and a posterior-side mounting portion in which the posterior-side stay portion is inserted.

3. The canister structure for a saddle riding vehicle according to claim 2 , wherein the anterior-side stay portion extends from an inferior portion of the canister obliquely upwardly toward a front and the posterior-side stay portion extends from an inferior portion of the canister obliquely upwardly toward a rear.

4. The canister structure for a saddle riding vehicle according to claim 1 , wherein
the purge valve is disposed on an upper portion of the canister via the canister rubber, and
the canister is connected with the purge valve by a purge line.

5. The canister structure for a saddle riding vehicle according to claim 1 , further comprising:
a guard disposed on an opening formed by an annular portion of the canister rubber, the guard covering the canister, wherein
the guard has a mounting tab, and
the canister rubber further includes, formed on the outer periphery thereof, a guard mounting portion that has a mounting tab insertion hole in which the mounting tab of the guard is inserted.

6. The canister structure for a saddle riding vehicle according to claim 1 , wherein at least either one of the vehicle body-side mounting portion and the purge valve mounting portion protrudes from the outer periphery of the canister rubber outwardly in a radial direction.

7. The canister structure for a saddle riding vehicle according to claim 3 , wherein the anterior-side stay portion and the posterior-side stay portion are formed separately from each other.
