Zusammenfassung: | PROBLEM TO BE SOLVED: To manufacture a closed vessel capable of absorbing volume increase of thermal storage medium with a simple structure. SOLUTION: This evaporated fuel treatment device is provided with a canister filled with adsorbent capable of adsorbing evaporated fuel in a fuel tank, and the thermal storage medium 17 inhibiting temperature change of an inside of the canister with using latent heat of coagulation and dissolution. The heat storage medium 17 is installed in the canister under a condition that the same is stored in the closed vessel 40. A space S capable of absorbing volume increase of the thermal storage medium 17 is provided between an inner wall surface of the closed vessel 40 and a surface of the thermal storage medium 17 in the closed vessel 40.
