Claims

[Scope of utility model registration request]

A control valve element formed inside the main body that simultaneously opens and closes a water flow path and a hot water flow path on one axis, and the control valve element is moved in the axial direction to adjust the valve opening degrees of the water flow path and the hot water flow path. and a temperature-sensing function section that is included in the operating system of the adjustment handle and moves the control valve body in response to the temperature of the mixed water. The thermostatic mixing valve is provided with a temperature sensing element that makes a pin appear and retract, and moves the control valve body by the operation of the pin, wherein the temperature sensing element is slidable in the axial direction of the control valve body. A guide supported in a honeycomb manner between the mechanism on the adjustment handle side is composed of an annular seal ring through which the temperature sensing element is inserted and a reinforcing ring integrally sealed inside the seal ring, and the seal ring is 2. A thermostatic mixing valve, characterized in that a tongue piece is formed from the surface exposed to the flow path inside the main body to the inner periphery thereof, the tongue piece coming into close contact with the outer circumferential surface of the temperature sensing element.
