Claims (1)

[Scope of Claim for Utility Model Registration] 1. A valve case that has an oblong cylindrical shape that follows the internal shape of the faucet body and has a water supply hole and a hot water supply hole drilled in the horizontal direction of the peripheral wall, and a valve case that is installed in the valve case. a valve body having a water stop edge facing the water supply hole and a hot water stop edge facing the hot water supply hole; and a valve body that is loaded into the valve case adjacent to the hot water stop edge of the valve body and is directed to the discharge port of the faucet body. a mixing case having a suitable discharge passage communicating therewith; a flow rate adjustment handle provided at one end of the faucet body or valve case and having a sliding end for the mixing case; and the other parts of the faucet body or valve case. a temperature setting part provided at an end and having a sliding prevention surface facing the valve body; a temperature sensing part fixed to the valve body and facing into the mixing case; and a temperature setting part that comes into contact with the sliding prevention surface of the temperature setting part. It consists of a temperature-sensitive elastic body provided with an elastic part, and a return spring that is located inside the mixing case and urges the valve body or the temperature-sensitive elastic body out of the case. A hot water valve seat made of an elastic material is provided facing the water stop edge of the valve body, and a water valve seat made of an elastic material is provided on the inner peripheral surface of the valve case facing the water stop edge of the valve body. In the stopper structure provided for the mixing faucet, a circumferential gap is formed between the inner circumferential surface of the valve case and the outer circumferential surface of the valve body, and within the circumferential gap there is provided a stopper structure for the mixing faucet. An annular valve body surrounding wall is provided that protrudes from the outer periphery of the hot water valve seat toward the outer peripheral surface of the valve body, and the valve body surrounding wall has a hot water stop edge of the valve body and a hot water valve of the valve case. A stopper structure for a hot water mixing faucet, characterized in that a hot water through hole communicating with a hot water side supply path formed between the seat and the seat is bored. 2. The valve body surrounding wall provided in the circumferential gap between the valve case and the valve body is formed as a separate body from the mixing case and is loaded while being separated, and the valve body surrounding wall is provided with the water supply of the valve case. A stopper structure for a hot water mixing faucet according to claim 1, characterized in that a pressure receiving step facing the hole is formed.
