Abstract: Provided is a temperature sensitive actuator attaching structure wherein the ease of attachment is improved. A heat generating element (51) generates heat by energizing a temperature sensitive actuator (2) via conducting terminals (41, 42). The generated heat expands a wax (W) to project a piston (21), and an elastic member (23) biases the piston (21) in a direction opposite to the projecting direction. In order to attach the temperature sensitive actuator (2) to an attachment portion (11) of an object member (1), fixing protrusions (41a) are provided in the conducting terminal (41) of the temperature sensitive actuator (2), and receiving portions (14) which can receive the fixing protrusions (41a) in a direction perpendicular to the axis of the piston (21) are provided in the attachment portion (11). The temperature sensitive actuator (2) is attached to the object member (1) by inserting the fixing protrusions (41a) into the receiving portions (14).
