In order to control the flow of water between them, a piston 3 serving as a valve body is slidably inserted in a direction traversing the main water passage 2. Since a thread groove 17 is formed on the upper part of the branch faucet 1 so that it can be screwed into a water pipe as a connecting portion, tap water can be screwed into a threaded portion provided at the end of a water pipe not shown. It has a structure that allows water to flow through the branch faucet 1 without leaking.

Two O-rings 4 are mounted on the outer peripheral surface of the piston 3 in order to maintain watertightness. Also, the piston 3
A rod 5 having a diameter smaller than that of the piston 3 is integrally connected to the valve retainer 6. The valve retainer 6 is attached to the branch faucet 1 by screwing, and an O-ring 7 is attached to enhance watertightness of the screwed portion. In addition, an O-ring 8 is held by a washer 9 on the valve retainer 6 in order to enhance the water honey in the portion where the rod 5 penetrates.

The projecting end of the rod 5 is a cylinder 19 which engages with the vertical opening 18 of the valve retainer 6, and the projection 20 provided on the cylinder 19 is spirally provided on the inner wall of the knob 10. The groove 21 can be slid. When the knob 10 is rotated, the protruding piece 20 moves according to the groove 21, and the cylinder 19 moves to the left and right of the opening hole 18. As a result,
The piston 3 can be freely slid in the sliding space A.

A branch port 11 is attached to the branch faucet 1 by screwing on one end face side on the left side in the drawing in the sliding space A. A branch water channel 12 communicating with the sliding space A is provided in the branch port 11, and the branch port 11 is connected via a hose or the like to a water conditioner or the like that generates negative and positive water by electrolysis (not shown). It can be done. In addition, in order to enhance the honeydew property at the threaded portion,
An O-ring 13 is attached.

Therefore, as shown in the figure, the piston 3
In the state where is moved to the one end face side of the sliding space A on the left side in the figure, the branch passage 12 of the branch port 11 is closed by the piston 3. That is, since the piston 3 does not intervene in the main water passage 2, tap water flows through the opening 15, the outer periphery of the rod 5, and the opening 16, and the main water passage 2 is open. On the contrary, by rotating the knob 10,
When the piston 3 is moved to the other end surface of the sliding space A on the right side in the drawing to close the opening 16, tap water flows from the opening 15 to the branch water passage 12, so that the water passage in this case is the main water passage 2 It will be communicated via the sliding space A. On the other hand, the main waterway 2 is closed.

As described above, the upper water inlet side connection portion of the main water channel 2 of the branch faucet 1 is provided with the thread groove 17 which can be screwed into the water pipe terminal, and the water pipe terminal is also provided with the thread groove. The pipe end and the branch faucet 1 are screwed together. Therefore, the direction of the branch port 11 screwed to the branch faucet 1 is uniquely determined in the screwed state. Since the water conditioner is installed at the branch port 11 through the branch water channel 12, the water supply direction of the water conditioner is constant, and there is no degree of freedom in the branch water channel. Therefore, it was difficult to attach the water conditioner and it was difficult to handle.
