ABSTRACT:
A first connecting pipe of an electromagnetic valve connects with the fuel tank, and a second connecting pipe connects with a canister. A spring urges a moving core and a first valve body in a closing direction of a electromagnetic valve. A shaft of the first valve body includes a fluid-amount controlling portion on the top. The fluid-amount controlling portion is inserted to the communicating passage while a contact member of bellows seats on a convex of a rubber member, and is tapered in an inserted direction. When a coil is energized, the first valve body is lifted in the direction in which the fluid-amount controlling portion retracts from the communicating passage.
