PROBLEM TO BE SOLVED: To appropriately and reliably perform heat receiving from a PTC heater for a temperature-sensitive part of a thermoelement in a required state. SOLUTION: A temperature-sensitive actuator 10 is configured to sense the temperature although a piston 14 is operated forcibly by generating heat from a PTC heater 20 and warming the temperature-sensitive part 13 of a wax thermoelement, wherein a contact member 40 is interposed between the temperature-sensitive part of the thermoelement and the PTC heater. Consequently, variation in the amount of heat which is received at the temperature-sensitive part of the thermoelement from the PTC heater is limited, and the stabilized output (lift amount) of the thermoelement can be ensured.
