The holding plate 43 is placed on the upper surface, and the holding plate 43 is stopped by the C ring 26 attached to the valve body. The decorative cover 29 is detachably attached to the upper end of the valve body 1, but the following structure is employed to prevent the valve shaft 11 and the decorative cover 29 from rotating together. A locking projection 45 projects downward from the back surface of the decorative cover 29, and is locked in a locking recess 46 provided at the upper end of the valve body 1.

[0003]

However, in the above-mentioned conventional example, in order to prevent the ball valve unit main body 25 from rotating together with the valve shaft 11 and the ball valve 9, the decorative cover 29 is provided with the valve shaft 11. There is a problem that the structure has to be complicated because it has to be stopped by different means in order not to co-rotate. When performing maintenance, the operation knob 10 and the decorative cover 29 are removed, and the C ring 26,
It is necessary to remove the co-rotation preventing member composed of the holding plate 43, the retaining pin 41, and the like, and remove the ball valve unit main body 25 and the like for maintenance, and there is a problem that workability and maintainability are poor.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a simple structure so that the ball valve unit main body and the decorative cover do not rotate together with the valve shaft. Another object of the present invention is to provide a bathtub flow path switching valve device that can be easily maintained.

[0005]

In order to achieve the above object, the present invention provides a bathtub flow switching valve device in which an inflow port 2 is provided at a lower portion of a valve body 1 and a foot side of a bathtub 3 is provided on both left and right sides of the valve body 1. And a back discharge port 5 communicating with the back side of the bathtub 3, and the foot discharge port 4 and the back discharge port 5 are provided.
The valve body 1 is provided with a shoulder discharge port 7 communicating with the shoulder nozzle 6 of the bathtub 3 above the valve body 1, and the valve body 1 is opened and closed between the inflow port 2 and the foot discharge port 4 and the back discharge port 5. And a ball valve 9 that opens and closes between the inflow port 2 and the shoulder discharge port 7 is rotatably mounted in the valve body 1, and the gate valve 8 and the ball valve 9 are connected to each other. In a bathtub flow path switching valve device in which a ball valve 9 is connected to a valve shaft 11 which is connected and rotated by an operation knob 10 so that a bather can switch the jet flow from a desired position, the valve body 1 A locking projection 31 projects from the back surface of the decorative cover 29 detachably attached to the upper end of the valve body 1 into the valve main body 1. Ball valve unit that is disposed between the outer periphery of the valve body and the inner periphery of the valve body 1 and rotatably supports the valve shaft 11. Wherein the the upper end of the locking recesses 33 of the preparative body 25 comprising locked the locking projection 31.

[0006]

According to the above construction, the locking projections 31 of the decorative cover 29 are locked to the locking recesses 32 of the valve body 1 and the locking recesses 33 of the ball valve unit body 25, so that the decorative cover 29 is The corotation of the ball valve unit main body 25 can be prevented, and the structure for preventing corotation can be simplified as compared with the related art. Also, when performing maintenance, if the operation knob 10 and the decorative cover 29 are removed, the ball valve unit main body 25 and the like can be easily removed, and maintenance can be facilitated.
