ABSTRACT:
A canister includes a casing that has a tank port connected to a fuel tank, an atmospheric port connected to an atmospheric passage communicating with atmosphere, and a purge port connected to an intake passage of an engine. An adsorbent is charged in the casing for adsorbing fuel vapor. A support member defines an accommodation chamber in the casing. The support member supports the adsorbent. A pump is supported by the support member. The pump is accommodated in the accommodation chamber. The pump introduces atmospheric air into the accommodation chamber through the atmospheric passage. A motor is accommodated in the accommodation chamber. The motor drives the pump. A damping member is located between the pump and the support member for absorbing sound and vibration transmitted from the pump to the support member.
