Abstract:
1. A canister, comprising: a tank port which communicates with an upper gas chamber of a fuel tank; a purge port which communicates with a suction path of an engine; an atmospheric port opened to the atmosphere; and an adsorptive material chamber which contains an adsorptive material to adsorb an evaporated fuel flowing from the tank port to the atmospheric port, wherein a thermal storage material made of a phase change substance which absorbs and discharges latent heat in response to a temperature change or a thermal storage material microcapsule containing the thermal storage material in a microcapsule is contained in a sealed container and is disposed in the canister, especially in the vicinity of the adsorptive material in a state in which the thermal storage material or the microcapsule is not brought into direct contact with the evaporated, the sealed container including the thermal storage material or the thermal storage material microcapsule is made of a material having a specific heat or a thermal conductivity which is larger than that of the adsorptive material, and the thermal storage material made of the phase change substance which absorbs and discharges the latent heat in response to the temperature change or the thermal storage material microcapsule containing the thermal storage material is contained in the sealed container made of a material which does not pass any gasoline vapor to constitute pellets, and said pellets are contained in the adsorptive material chamber together with the adsorptive material.
