As a technique for configuring another flow channel by using an existing faucet main body as it is, as seen in British Patent No. 1501161, the valve is attached to a cylindrical rising portion downstream of the valve seat of the faucet main body. A branch faucet block is screwed in contact with the valve seat, and the block has a water guide channel that communicates with the upstream flow channel via the valve seat channel, and an upper space of the channel that connects to the valve seat. The branch faucet has a water discharging channel that communicates with a downstream water channel, a valve seat is provided around the upper end of the water guiding channel, and a valve body that can freely come into contact with and separate from the valve seat. It is attached to the block so that the flow channel on the upstream side of the valve seat and the flow channel on the downstream side of the valve seat can be freely switched between a communicating state and a non-communicating state. When a branch pipe is connected for communication and a water stop valve is attached to this branch pipe, or when the water introduction channel and water discharge channel of the block are configured to be closable with the valve body, the water stop valve connection A branch pipe is provided in communication with the upper space of the block, so that the branch pipe constitutes a flow channel separate from the flow channel of the faucet itself that bypasses the flow channels of the water introduction and water discharge.

That is, when constructing a branch faucet, the branch faucet block is screwed onto the cylindrical rising portion of the faucet body in order to bring the gasket on the block side into close contact with the valve seat of the faucet body. However, the threading relationship between the male thread on the block side and the female thread on the faucet body side is unstable, and therefore, the relative phase of the branch pipe with respect to the faucet body cannot be set arbitrarily. ,
In other words, there was a drawback that the branch pipe could not be attached to the faucet main body at an arbitrary phase.

The present invention has been devised in view of the above-mentioned circumstances, and the branch faucet according to the present invention has a middle side wall of a spindle shaft that extends along the axial direction and has a hollow portion that is open at both upper and lower ends. A water outflow hole communicating with the hollow portion is provided, and an annular gasket is attached to the periphery of the lower end opening, and the spindle shaft is attached to a faucet body having a discharge port so as to be movable in the axial direction, and the gasket is attached. A joint member configured to be able to come into contact with and separate from the valve seat of the faucet body, and communicating with the water outflow hole to form a branch flow path, is attached to the spindle axis relative to the faucet body. An on-off valve is provided in the branch flow path, and an upper end blocker is provided in the upper end opening of the spindle shaft, the upper end blocker having an air hole for preventing backflow that communicates with the outside from the hollow portion. Attach an upper end blocker having an air hole for preventing backflow that communicates with the outside from the hollow portion to the upper end opening, and apply a ball valve to the inner end of the air hole of the blocker via a spring. When water is supplied, the valve comes into contact with the inner end of the air hole due to the pressure inside the hollow part to close the air hole, and when water is cut off, the valve separates from the air hole and opens the air hole due to a pressure drop. It has characteristics.
