Claims

[Claims for Utility Model Registration] A substantially annular flange portion supported in a flow path, a valve seat formed on the inner periphery of this flange portion, and a substantially plate-shaped valve body that approaches and separates from the valve seat. , a spring frame protruding from one side of the flange portion, a spring provided between the spring frame and the valve body to press the valve body against the valve seat, and a thermal expansion body such as wax built therein; This thermal expansion has the function of protruding the piston rod,
a thermoelement that is attached to the valve body through a piston guide that guides a piston rod;
In the thermostat, the thermostat includes a contact member that is protruded from the other side of the flange portion, abuts the tip of the piston rod of the thermoelement, and causes the valve body to be pulled away from the valve seat by the protrusion of the piston rod, the piston guide comprising: A circumferential groove formed on the outer periphery;
A ring body having a substantially circular cross section and fitting into the circumferential groove and protruding to the outer periphery; and a ring body formed at the periphery of the piston guide insertion hole of the valve body, protruding short toward the spring frame, and contacting the ring body to guide the piston guide into the valve body. 1. A thermostat characterized in that it has a protruding edge that is slightly tiltable with respect to the body and that allows the valve body to be tilted and brought into close contact with the valve seat.
