 The hot and cold water mixing tap according to the present invention, which has achieved the above object, is a mixing tap attached to a hot and cold water supply pipe opened upward in the vicinity of a horizontal faucet mounting surface part, respectively. A screw body screwed to the screw connection portion is rotatably provided in the hot water and water introducing member connected to the mixing chamber of the mixing stopper main body through a connecting pipe, and water such as a constant flow valve or a strainer is provided. It is characterized in that a water faucet member loading portion for loading the faucet member from above the faucet mounting surface portion is formed in the introduction member.

[0006]

[Action]

 According to the above characteristic configuration, a wide space above the faucet mounting surface portion is used as a working space, and the screw body on the main body side of the mixing stopper is screwed into the screw connection portion opened upward near the faucet mounting surface portion. Thus, the mounting of the hot and cold water mixing stopper on the faucet mounting surface portion is achieved. In addition, the hot and cold water mixing tap can be replaced in the upper space of the faucet mounting surface by unscrewing the screw body, or the maintenance of various faucet members after the mixing tap is installed does not interfere with anything. It can be done in a large open space above the faucet mounting surface that is not closed.
