Thus, the inclination angle θ in the optical axis direction L of the human sensor relative to the bottom surface part 5b of the operation case 5 can be secured by the inclination of the human sensor relative to the sensor case 41 and the inclination of the window part 41b of the sensor case 41. Accordingly, since the inclination of the window 41b of the sensor case 41 can be made gentle, the sensor case 41 becomes less conspicuous from the user side and the appearance is improved.

  Next, an example of the assembly procedure of the mixing tap 1 will be described.

  First, the fixing plate 5B is fixed to the rear plate 18 (FIGS. 2 and 3) of the mirror cabinet located above the rear part of the wash bowl, and then, as shown in FIG. 7, the inside of the cartridge holder 3b attached to the fixing plate 5B. After the cartridge main body 3a is housed, the cartridge cover 3c is covered, and the lever cover 2c is mounted with the rotating shaft 2a of the operation lever 2 attached to the valve shaft 3d of the cartridge main body 3a with the screw 16. At this time, the lever cover 2c is inserted into the outer peripheral concave portion 7b of the cartridge cover 3c while inserting the operation portion 2b of the operating lever 2 into the cover hole 2d of the lever cover 2c, and the lever cover 2c is moved with a tool or the like. Can be easily installed without using. On the other hand, the hose 23 of the water discharge head 4 is drawn from the front of the fixing plate 5B to the rear of the back plate 18 through the inside of the hose guide 22 and connected to the mixed water outlet of the faucet cartridge 3. Thereafter, the operation case body 5A is attached to the fixed plate 5B. At this time, the central convex portion 6a of the lever cover 2c is fitted into the central concave portion 6b on the inner surface of the operation case body 5A, and the operation portion 2b of the operation lever 2 is moved downward from the operation opening 9 on the bottom surface of the operation case main body 5A. Further, the lower end portion of the fixing plate 5B and the lower end portion of the rear portion of the operation case body 5A are moved downward with the rear upper end of the operation case body 5A hooked and locked to the engaging claw 30 at the upper end of the fixing plate 5B. Fasten with screws 31 (FIG. 4). Thereby, the assembly and attachment of the operation case 5 are completed.

  Thus, the water discharge head 4, the operation lever 2, and the faucet cartridge 3 can be installed in a well-contained manner along the lower end surface of the mirror cabinet 13 of the vanity table 10. In addition, the operation lever 2 can be operated from the outside through the operation opening 9, and in addition, the connection portion between the operation lever 2 and the faucet cartridge 3 is not exposed to the outside from the operation opening 9 by the lever cover 2c. In addition, since the operation opening 9 is provided in the bottom surface portion 5b of the operation case 5, the operation opening 9 and a part of the lever cover 2c and a part of the faucet cartridge 3 exposed from the user are conspicuous. It disappears and looks better.

  Further, since the exposed portion of the lever cover 2c exposed from the operation opening 9 of the operation case 5 and the exposed portion of the faucet cartridge 3 are flush with each other, there are steps or gaps at the boundary between these exposed portions. Or the like, and it becomes difficult for dust to accumulate. Therefore, the operation is not hindered, and the labor of cleaning the lever cover 2c can be saved.

  Further, in this example, since the operation case 5 is attached to the back plate 18 of the mirror cabinet 13, there is an advantage that it is not necessary to provide a conventional curan attachment hole, a lever attachment hole or the like on the existing wash bowl 15 side.

  On the other hand, at the time of maintenance, the operation case body 5A is removed from the fixed plate 5B, and then the lever cover 2c is removed. At this time, the lever cover 2c is lowered in such a direction that the outer peripheral convex portion 7a of the lever cover 2c is removed from the outer peripheral concave portion 7b of the cartridge cover 3c, and the lever 2 is pulled out of the cover hole 2d. The cover 2c can be easily removed without using a tool or the like. Thereafter, the maintenance operation of the faucet cartridge 3 can be easily performed by removing the rotation shaft 2a of the operation lever 2 from the valve shaft 3d of the cartridge body 3a.

  In the embodiment, the example in which the operation opening 9 for projecting the operation portion 2b is provided on the bottom surface portion 5b of the operation case 5 has been described, but the position of the operation opening 9 is not necessarily the bottom surface portion of the operation case 5. For example, the operation case 5 may be provided on the side surface portion or the front surface portion 5a.
