ABSTRACT:
A canister is comprised of a casing including a top wall, a vertical wall, first and second chambers formed in the casing and each accommodating an adsorbent, and a partition member partitioning the first and second chambers from each other. A plurality of first protuberances are formed on the inner surface of the top wall at a portion thereof facing toward the first chamber, and a plurality of second protuberances on the inner surface of the vertical wall at a portion thereof facing toward the first chamber. First and second filters are mounted in the first chamber in a fashion abutting on the plurality of the first and second protuberances, respectively. A first space is defined in the top wall between the first filter and the portion of the inner surface of the top wall, and a second space is defined in the vertical wall between the second filter and the portion of the inner surface of the vertical surface and communicates with the first space. A charging port and a purging port are each formed in the top wall at a location corresponding to the first chamber and each open into the first space. An atmospheric air port is formed in the top wall at a location corresponding to the second chamber.
