A thermostat includes an annular flange extending in radial directions and surrounded by a cylindrical large-diameter portion of a housing inner surface, and a frame extending in axial directions from the flange. The thermostat further includes a sealing member that hermetically seals the gap between the flange and the inner surface. The sealing member includes an annular outer peripheral portion sandwiched in the axial directions by the inner surface and a thermostat cover inside the large-diameter portion, and a plurality of protruding portions extending outward in the radial directions from the outer peripheral portion toward the large-diameter portion. The thermostat is disposed inside a housing that defines a portion of a cooling water passage, and opens and closes the cooling water passage according to the temperature of cooling water inside the cooling water passage.
