The mixed hot water is supplied from a water spout 13 at the end of a water spout pipe 12, and switching between water supply and water stop is performed by moving the valve body 2 up and down. Further, a detection sensor 14 is provided near the water spout 13 at the end of the water spout pipe 12.
The cord 15 of the detection sensor 14 is passed through the water discharge pipe 12 and pulled out downward. The drive control device 3 is capable of protruding or retracting a drive shaft 4 by driving a motor (not shown), and the drive shaft 4 is inserted into an extension pipe 17 fixed to a bearing 16 to be driven. An upper end is made to protrude from the upper surface of the control device 3. In order to control the valve body 2 of the faucet body 1 by the drive control device 3, it is necessary to connect the drive shaft 4 and the valve body 2 with a flexible wire 6, and the connection is made in the following structure. That is, a cartridge guide 18, which is a non-movable part, is attached to the lower surface of the faucet main body 1, and a flexible sleeve 5 such as a mesh wire tube, a thin-walled plastic tube, or a metal flexible tube is attached to this cartridge guide 18. One end is fixed with a nut 19 as shown in FIG. Also,
One end of the flexible wire 6, such as a metal wire, that is passed through the flexible sleeve 5 is inserted into the metal tube 20 at the center of the valve body 2, as shown in FIG. 3, and the metal tube 20 is caulked to the tip. It is fixed with the crimping part 21 and the metal tube 20
At the tip of the metal tube 20 and the flexible wire 6 are fused with solder 22 or wax. A ball 23 with a hole in the center is inserted into the other end of the flexible wire 6 as shown in FIG. The ball 23 is positioned at an appropriate position and fixed by a set screw 24 screwed into the ball 23. The sleeve 2 is attached to the end of the flexible wire 6 before the ball 23 is attached.
5 is inserted through the sleeve 25, and the ball 23 is fitted into the sleeve 25 almost tightly.The sleeve 25 is rotatable around the flexible wire 6 for the sake of the ball 23, but the flexible wire 6 It's become impossible to get out of it. A female thread is formed on the inner periphery of the sleeve 25.
On the other hand, a male thread is formed at the upper end of the drive shaft 4, and the end of the flexible wire 6 is fixed to the drive shaft 4 by screwing the sleeve 25 onto the drive shaft 4. The sleeve 25 has a lock nut 2 to prevent loosening.
