In a canister and a method of manufacturing a canister, in order to restrain a temperature rise of an adsorptive material owing to adsorption of an evaporated fuel (gasoline vapor) or to restrain a temperature drop of the adsorptive material during purging of the adsorbed gasoline vapor and to increase adsorbing and purging amounts, or in order to improve adsorbing and purging performances of the evaporated fuel, there is disposed a thermal storage material constituted of a phase change substance which absorbs and discharges latent heat in response to a temperature change or a thermal storage material microcapsule constituted by confining the thermal storage material in a microcapsule in a state in which the material or the microcapsule is not brought into direct contact with the evaporated fuel, and especially in the vicinity of the adsorptive material in a heat-conduction state, so that the temperature change is restrained by the thermal storage material in response to the temperature rise or drop of the adsorptive material to prevent deterioration of the adsorbing performance of an activated carbon due to the temperature rise and deterioration of the purging performance of the activated carbon due to the temperature drop.

An accelerator device includes an accelerator armprovided with an accelerator pedal, a support caseinternally holding and supporting an arm base partthrough a support shaft, a return springandfor urging the armto rotate in a returning direction to return the pedalto an initial position, and an accelerator sensorfor detecting a rotation amount of the armas an accelerator opening degree. A hysteresis producing mechanism includes friction piecesandattached to the arm base part. A curved contact surfaceof the friction pieceis held in contact with a contacted surfaceof a friction partof the support case. One end of the return springandis hooked in one end of the friction pieceand, and the other end of the springandis connected to the arm base partin order to press the contact surfaceandof the friction pieceandagainst the contacted surfaceof the friction part
