A head member fixing ring having a coefficient of thermal expansion equivalent to that of the piston body is loosely fitted to the outer periphery of the small diameter portion, and the ring is fixed to the inner circumferential surface of the recess on the opening side. A heat-resistant elastic member is interposed between the heat-insulating head member and the ring and between the heat-insulating head member and the piston body.
