PROBLEM TO BE SOLVED: To provide a saddle riding type vehicle using an electronic throttle valve for controlling an engine speed, while suppressing or controlling the unexpected suction of evaporating fuel due to a position change of the throttle valve when sucking the evaporating fuel generated from a fuel tank into an engine. SOLUTION: An evaporating fuel purge device 70 consists of an evaporating fuel passage 71 for discharging evaporating fuel from the fuel tank 33, a canister 72 for temporarily trapping the evaporating fuel, and a purge pipe 73 for supplying the evaporating fuel into an intake passage 9. One end of the evaporating fuel passage 71 is connected to the upper part of the fuel tank 33, and the other end is connected to the canister 72. The upstream end of the purge pipe 73 is connected to the canister 72, and the downstream end is located on the upstream side beyond the upstream end of the throttle valve 11 when fully closed, and on the downstream side beyond the position of the upstream end of the throttle valve 11 when fully opened, in the longitudinal direction of the intake passage 9. In the purge pipe 73, an opening/closing device 75 is provided for opening/closing the purge pipe 73. COPYRIGHT: (C)2007,JPO&INPIT
