PROBLEM TO BE SOLVED: To provide an evaporated fuel treatment device having a canister and a sealing valve and adapted to be mounted on a vehicle, for simplifying mounting work in mounting the evaporated fuel treatment device on the vehicle.SOLUTION: Between a fuel tank 12 and a canister 40 for adsorbing/desorbing evaporated fuel to/from the fuel tank 12, an evaporated fuel passage 31 is provided into/out of which the evaporated fuel flows. In the evaporated fuel passage 31, a sealing valve 50 is provided for performing opening/closing operation so that the evaporated fuel flows into/out. In the sealing valve 50, a motor-operated valve 60 is provided which uses a stepping motor for shifting the position of a valve element relative to a valve seat to control the opening/closing operation so that the evaporated fuel flows into/out. The motor-operated on/off valve 60 is stored in and supported by a valve housing integrated with a canister case serving as the exterior of the canister 40.SELECTED DRAWING: Figure 2 |
