An wax-pallet thermostat has a valve seat (1), a piston (8) secured to the valve, a guide member (6) slidably mounted on the piston, a valve (4) secured to the guide member, a diaphragm (9) secured to the guide member, and an wax (10) provided in a cylinder (11). A gap is provided in the guide member around the piston so as to accumulate coolant which has entered along the piston. The gap is provided to discharge the coolant from the guide member when the wax expands to cause a part of the diaphragm to enter into the gap.
