Claims

[Scope of Claim for Utility Model Registration] Provided in the water supply pipe connected to the hot and cold water mixing faucet, when the water side of the hot and cold water mixing faucet is opened, it moves to the open position against the biasing force and releases the valve body from the valve seat. In a check valve that allows water to flow from the side to the secondary side, the check valve is provided with a relief hole for holding the valve body and communicating the primary side and the secondary side, and a secondary side of the relief hole is provided. A valve body holder having a valve accommodating portion at a lateral inlet; and a relief valve whose head is inserted into the valve accommodating portion of the valve body holder so that its base faces the secondary side and is movable in the direction of the flow path. a cap member that passes the base of the relief valve through the opening and is attached to the valve body receiver from the secondary side; and a cap member that is attached to the outer periphery of the base of the relief valve and is located between the head and the cap member within the valve housing. A check valve comprising: a sealing elastic member to be provided; and a biasing member that biases the relief valve toward the secondary side and compresses the sealing elastic member between its head and the cap member. .
