PROBLEM TO BE SOLVED: To reduce an uncomfortable sound which is generated in a valve device at valve-closing or the like.SOLUTION: A valve device opens/closes a flow passage which guides evaporated fuel from a fuel tank to a canister, and includes a valving element 22 which is driven in one linear direction, and is seated on a prescribed valve seat 34 to close a flow passage 20. Here, the valving element 22 has a rubber-made valve part 30, and the valve part 30 is seated on the valve seat 34 to close the flow passage 20. By that, after a part of the valve part is seated, the other portion other than the part of the valve seat 34 is seated on the valve seat 34 late, the valve part 30 is entirely seated on the valve seat 34. By this configuration, an impact when the valve part 30 is seated on the valve seat 34 is temporally diffused. The generation of a sound resulting from the impact can be thereby suppressed, and an uncomfortable sound which is generated in the valve device at valve-closing can be reduced. |
