The seal member 80 is sandwiched between the locking step portion 57 of the water discharge member 40 and the recess 39 of the hand-washing device 20, and water leakage between the through-hole 35 of the hand-washing device 20 and the water discharge member 40 is restricted.

  The entire seal member 80 is disposed in the recess 39. The main body portion 41 of the water discharge member 40 is provided so as to cover the seal member 80 when the proximal end portion of the main body portion 41 is viewed from the surface side of the hand-washing device 20.

  FIG. 5 is a side cross-sectional view showing the recess 39 and the seal member 80 when the water discharge member 40 is removed from the hand-washing device 20. The recess 39 has L1 [mm] as its depth dimension. The depth dimension here means a dimension in the normal direction of the virtual plane P from the virtual plane P in contact with the seating surface 31 to the concave bottom surface 39a. In FIG. 5, the imaginary plane P and the opening edge of the recess 39 overlap.

  The seal member 80 has a thickness dimension of L2 [mm] when not elastically deformed. The thickness L2 of the seal member 80 is determined to be larger than the depth L1 of the recess 39.

  As shown in FIG. 4, the seal member 80 is sandwiched between the concave portion 39 of the hand-washer 20 and the locking step portion 57 of the water discharge member 40 so as to be elastically deformed in the thickness direction. At this time, the seal member 80 is elastically deformed at a portion extending over the entire circumference in the circumferential direction, and contacts so that the radial side surface 81 is in close contact with the concave side surface 39b of the recess.

  Next, a method for attaching the water discharge member 40 to the handwasher 20 will be described. First, the insertion shaft portion 43 of the water discharge member 40 is inserted into the through hole 83 of the seal member 80. The seal member 80 is moved until it engages with the locking step portion 57 of the water discharge member 40.

  The insertion shaft portion 43 of the water discharge member 40 is inserted into the through-hole 35 from the seat surface 31 side of the handwasher 20. The water discharge member 40 is moved until the locking step 57 is seated on the seat surface 31 of the hand-washing machine 20. Thereby, the insertion shaft part 43 protrudes from the through-hole 35 to the back surface side of the hand-washing machine 20.

  At this time, the seal member 80 moves along the insertion direction of the insertion shaft portion 43. Here, when the concave side surface 39b of the concave portion 39 is provided perpendicular to the seat surface 31, the opening edge 39c (FIG. 5) located at the high position of the concave portion 39 is formed on the seal member 80 that moves along the insertion direction. (See) is caught. In this regard, in the present embodiment, since the concave side surface 39b of the concave portion 39 is formed along the axial direction of the insertion shaft portion 43, the seal member 80 can be prevented from being caught by the opening edge 39c of the concave portion 39. Therefore, the sealing member 80 can be stably moved to the bottom side of the concave portion 39, and the workability at the time of assembling the hand washing apparatus 10 is improved.

  Then, the insertion part 73 of the fixing tool 70 is inserted between the base end side step part 50 and the front end side step part 51 of the water discharge member 40, and the water discharge member 40 is fixed to the hand-washer 20.

  According to the hand-washing apparatus 10 according to the above embodiment, the gap between the through hole 35 of the hand-washing machine 20 and the water discharge member 40 can be sealed by the seal member 80. In particular, since the radial side surface 81 of the seal member 80 is in contact with the concave side surface 39b of the concave portion 39, the surface area contributing to sealing is increased and the sealing performance is improved as compared with the case where the seal member 80 is not disposed in the concave portion 39. Moreover, since the sealing member 80 is arrange | positioned in the recessed part 39, exposure of the sealing member 80 is suppressed in the external appearance of the hand-washing machine 20, and the design property becomes favorable.

  Further, the thickness dimension L <b> 2 of the seal member 80 is larger than the depth dimension L <b> 1 of the recess 39. Therefore, when the water discharging member 40 is attached to the hand-washing device 20, the seal member 80 is easily crushed between the hand-washing device 20 and the locking step portion 57 reliably.

  Moreover, since the water discharging member 40 is fixed in a state where the locking step portion 57 is seated on the seat surface 31, the amount of collapse of the seal member 80 does not become excessively large. In the case where there is no recess 39, when the seal member 80 is sandwiched between the seat surface 31 of the hand-washing machine 20 and the locking step portion 57 of the water discharge member 40, it is difficult to adjust the amount of crushing. When this amount of crushing is excessively large, the elastic repulsion force by the seal member 80 increases. Therefore, when the water discharging member 40 is to be fixed to the hand-washing device 20 by the fixing tool 70, the water discharging member 40 is likely to be displaced in the direction P1 (see FIG. 4) that is pulled out from the through hole 35 due to the elastic repulsive force of the seal member 80. It becomes difficult to attach the fixture 70. In this regard, according to the present embodiment, since the amount of collapse of the seal member 80 does not become excessively large, the displacement of the water discharge member 40 due to its elastic repulsion can be suppressed, and the workability when assembling the hand washing apparatus 10 is good. Become.

  Further, since the water discharging member 40 is fixed in a state where the locking step portion 57 is seated on the seat surface 31, the seal member 80 is formed in an annular shape, and therefore the amount of crushing in the circumferential direction of the seal member 80 is excessively large. Can be adjusted evenly. When the amount of crushing is not uniform in the circumferential direction, the main body portion 41 of the water discharging member 40 is easily inclined with respect to the seat surface 31 of the hand-washing device 20 due to the elastic repulsive force of the seal member 80. In this regard, according to the present embodiment, the inclination of the main body portion 41 due to the elastic repulsive force of the seal member 80 can be suppressed, and it is difficult to form a large gap in a part in the circumferential direction between the main body portion 41 and the seat surface 31. Appearance quality is improved.

  Moreover, since the main-body part 41 of the water discharging member 40 is provided so that the seal member 80 may be covered, exposure of the seal member 80 is suppressed more in the external appearance of the hand-washing machine 20, and the design property becomes more favorable.
