Further, the heights of the convex spline 62c and the concave spline 64b are configured to be lower than the height of the protrusion 34d (not shown in FIG. 6) formed on the faucet cartridge 28.

  Next, an assembling procedure of the faucet unit 60 according to this modification will be described. First, the faucet cartridge 28 is dropped into the receiving portion 64a of the lower main body 64 so that the operation lever 40 protrudes downward. Next, the cylindrical portion 62a of the upper body 62 is inserted into the receiving portion 64a. At this time, the rotational position of the upper body 62 is adjusted so that the protrusion 34d of the faucet cartridge 28 is received in the recess formed on the lower end surface of the upper body 62.

  Here, since the height of the protrusion 34d of the faucet cartridge 28 is configured to be higher than the height of the convex side spline 62c and the concave side spline 64b, the protrusion 34d is received in the concave part of the upper body 62, and the spline is engaged. The upper body 62 can be held at a position that is not aligned. In this state, the upper body 62 is rotated with respect to the lower body 64, and the upper body 62 is moved to a predetermined rotational position. At this time, since the protrusion 34 d is received in the recess of the upper body 62, the faucet cartridge 28 is also rotated together with the upper body 62. After the upper body 62 is moved to a predetermined rotational position, the convex side spline 62c and the concave side spline 64b are engaged, and the rotational position of the upper body 62 with respect to the lower body 64 is fixed. Finally, the cap nut 30 is screwed into the male screw 64c on the outer peripheral upper end of the lower body 64, and the upper body 62 and the lower body 64 are joined. Further, since the operation handle 10, the handle cover 52, and the like are attached in the same manner as in the above-described embodiment, the description thereof is omitted.

  As mentioned above, although preferable embodiment of this invention was described, a various change can be added to embodiment mentioned above. In particular, in the above-described embodiment, the operation lever of the faucet device is configured to protrude downward in the vertical direction, but the protruding direction of the operation lever may be other than vertically downward. In the present specification, “the operation lever protrudes downward” includes all the operation levers extending in a direction below the horizontal plane.
