PROBLEM TO BE SOLVED: To efficiently arrange a purge pipe provided with a valve member at a periphery of a vehicle body frame in a canister arrangement structure of a saddle-riding type vehicle in which a canister is disposed in an area located at the rear side of a cylinder of an internal combustion engine and above a crank case.SOLUTION: A purge pipe 62 wich guides an evaporative fuel adsorbed by a canister 40 to a vaporizer 22 is connected to the canister 40. A non-return valve 62a is provided in the middle of the purge pipe 62. The purge pipe 62 extends from the canister 40 to the upper side and traverses an area near a main frame 5 in a vehicle crosswise direction to be connected with a throttle part 22. The non-return valve 62a is supported by the main frame 5.
【課題】内燃機関のシリンダの後方かつクランクケースの上方にキャニスタを配置した鞍乗り型車両のキャニスタ配置構造において、弁部材を設けたパージ管を車体フレーム周辺に効率よく配置する。【解決手段】キャニスタ40には、該キャニスタ40で吸着されている蒸発燃料を気化器22へ導くパージ管62が接続され、パージ管62の途中には逆止弁62aが設けられ、パージ管62は、キャニスタ40から上方に延びた後、メインフレーム5近傍を車両左右方向で横断して、スロットル部22に接続されるとともに、逆止弁62aは、メインフレーム5に支持される。【選択図】図5
