Abstract
Provided is a canister whose performance is enhanced while achieving the advantage of suppressing changes in temperature by using a heat storage material and overcoming the disadvantage of a reduction in the adsorption amount. A canister for treating evaporated fuel includes: a tank port that is in communication with an upper air chamber of a fuel tank of an internal combustion engine; a purge port that is in communication with an air intake path of the internal combustion engine; an atmospheric air port that is open to atmospheric air; and an adsorbent material chamber R that contains an activated carbon that adsorbs evaporated fuel that flows from the tank port to the atmospheric air port. A heat storage material is provided in a tank-side adjacent region T of the adsorbent material chamber R that is provided adjacent to the tank port, the heat storage material being a material obtained by encapsulating, into capsules, a phase change material that absorbs and releases latent heat according to changes in temperature.
