Abstract
A valve device includes an outflow port inserted in an engine port provided on an intake pipe so as to communicate with an intake passage. A leak port is inserted in the engine port and includes a leak passage into which evaporative fuel is allowed to flow regardless of a permitting state and a blocking state. A seal provides a sealed state between the outflow port and the engine port. Another seal provides a sealed state between the leak port and the engine port. The seal is positioned such that the sealed state of the seal becomes broken before breakage of the other seal when the outflow port and the leak port move in a direction away from the engine port.
