Abstract: A cylindrical column-shaped honeycomb adsorbent has a plurality of cell passages extending along an axial direction of the honeycomb adsorbent. The plurality of cell passages are configured so that a pitch of adjacent cell passages is within a range of 1.5 mm˜1.8 mm, and so that a thickness of a wall between the cell passages is within a range of 0.45 mm˜0.60 mm. With this configuration, the honeycomb adsorbent exhibits BWC (Butane Working Capacity) of 6.5 g/dL or greater. By mixing fibrous meltable core melting away during baking, the honeycomb adsorbent has macropores configured to have a volume of 0.15 mL/g˜0.35 mL/g with respect to an overall weight of the honeycomb adsorbent and metal oxide particles having a proportion of weight of 150˜250% with respect to the activated carbon.

Abstract: A canister is provided with a plurality of adsorbent chambers filled with adsorbent, and the adsorbent chambers are connected together so as to form a U-turn-shaped passage. The canister has a communication chamber through which both end portions of adjacent two adsorbent chambers communicate with each other; a middle chamber formed at the end portion of one of the adjacent two adsorbent chambers, which is positioned at a downstream side of the communication chamber, and connected to the communication chamber through a communication hole; a baffle plate set in the middle chamber with the baffle plate facing to the communication hole so that an incoming air flow from the communication hole strikes against the baffle plate and diffuses in the middle chamber; and a tubular portion protruding in the communication chamber from an opening edge of the communication hole along a longitudinal direction of the one adsorbent chamber.
