To provide a thermally driven valve having a structure which enables improvement of adhesion between a heater and a wax thermoelement.SOLUTION: In a thermally driven valve, a valve body 13, a wax thermoelement 15 for driving the valve body, and a heater 16 for heating the wax thermoelement are disposed serially in a thermally driven valve case. The heater has: a heating surface 16a with which the wax thermoelement is placed in contact; and a support surface 16d opposite to the heating surface 16a. The thermally driven valve case is provided with a heater support part 7a which protrudes so as to make point contact with a position near a center of the support surface.SELECTED DRAWING: Figure 3 【課題】ヒータとワックスサーモエレメントの密着性を向上させる構造を有する熱動弁を提供すること。【解決手段】弁体１３と、この弁体を駆動するためのワックスサーモエレメント１５と、このワックスサーモエレメントを加熱するためのヒータ１６とが熱動弁ケース内に直列状に配設された熱動弁において、ヒータはワックスサーモエレメントに当接させる加熱面１６ａとその反対側の支持面１６ｄを有し、熱動弁ケースには支持面の中央近傍に点接触状に当接するように突出させたヒータ支持部７ａを設けた。【選択図】図３
