In FIG. 6, the figure which looked at the insertion shaft part 53 from the diagonal lower side of the hand-washing machine 20 is shown. The mounted portion 65 and the retaining step portion 81 are formed on a part of the insertion shaft portion 53 that protrudes from the through hole 35 to the back side when the locking step portion 55 of the water discharge member 50 is seated on the seat surface 31. At this time, the retaining step portion 81 of the water discharge member 50 is provided to face the opening 42 of the through hole 35 formed on the back surface 24 side of the hand-washing device 20 in the vertical direction Z.

  FIG. 7 is a cross-sectional view taken along line EE in FIG. The retainer 90 is a clip. The retainer 90 includes a base portion 91, a pair of insertion portions 93 extending from the base portion 91, and a claw portion 95 formed inside each of the pair of insertion portions 93. Each part of the stopper 90 is integrally formed of a resin material or the like.

  The base 91 is formed in an arc shape, and a protrusion 97 is provided on the inner peripheral side thereof. The insertion part 93 is formed in a plate shape extending along one direction, and can be elastically deformed in a direction to widen a gap between the pair of insertion parts 93. The retainer 90 is disposed so that the mounted portion 65 is positioned between the insertion portions 93.

  The claw portion 95 of each insertion portion 93 is engaged with the engaged portion 77 of the attached portion 65 by snap fitting, and the retaining member 90 is detachably attached to the attached portion 65 by the engagement. When the retainer 90 is pulled strongly toward the outer peripheral side of the base 91, the pair of insertion portions 93 are elastically deformed in a direction to widen the gap, the engagement of the claw portions 95 is released, and the retainer 90 can be removed.

  When the stopper 90 is in the mounting position where it is mounted on the water discharge member 50, the inner peripheral surface of the protrusion 97 that is the inner peripheral portion of the base 91 comes into contact with the sliding portion 79 of the mounted portion 65.

  8 is a cross-sectional view taken along line FF in FIG. FIG. 9 is a partial cross-sectional perspective view showing a state in which the retainer 90 is mounted on the mounted portion 65. In FIG. 9, the figure which looked at the insertion shaft part 53 from the diagonally lower side of the hand-washing machine 20 is shown.

  Each insertion portion 93 of the stopper 90 is inserted between the opening 42 of the through hole 35 and the stopper step 81 of the water discharge member 50. This insertion direction is a specific direction P (see FIG. 7) that intersects the axial direction of the insertion shaft portion 53. By this insertion, the stopper 90 is interposed between the peripheral edge 43 of the opening 42 and the stopper step 81. When the insertion shaft portion 53 of the water discharge member 50 tries to come out of the through hole 35, the stopper 90 that comes into contact with the removal step portion 81 of the insertion shaft portion 53 tries to move integrally with the water discharge member 50. At this time, the distal end portion 93 a and the base portion 91 of each insertion portion 93 come into contact with the peripheral edge portion 43 of the opening 42, and the insertion shaft portion 53 is prevented from coming off from the through hole 35. The retainer 90 fixes the water discharge member 50 in the axial direction of the insertion shaft portion 53.

  As shown in FIGS. 6 and 7, a guide portion 45 is provided on the radially outer side of the insertion shaft portion 53 from each insertion portion 93. The guide portion 45 is provided so as to protrude downward from a part of the peripheral edge portion 43 of the opening 42, which is the tip side of the insertion shaft portion 53. Moreover, the guide part 45 is integrally molded as a part of the protruding part 33 of the hand-washing machine 20.

  The guide portion 45 is formed such that the inner side surface 45 a on the radially inner side extends along the insertion direction P. A taper portion 46 is formed on the inner surface 45a of the guide portion 45 so that the distance from the insertion portion 93 becomes narrower from the entry side (right side in FIG. 7) to the exit side (left side in FIG. 7) in the insertion direction P. It is formed.

  As shown in FIG. 9, a mounting restricting portion 48 is provided on the peripheral edge 43 of the opening 42 by a protrusion protruding downward from the front portion in the front-rear direction Y. In addition, a space 49 is provided on the distal end side of the insertion shaft portion 53 from the peripheral edge portion 43 to allow the distal end portion 93a to move when the insertion portion 93 is inserted between the opening 42 and the retaining step portion 81. The spaces 49 are provided on both sides in the left-right direction X from the mounting restricting portion 48.

  Next, a method for attaching the water discharge member 50 to the handwasher 20 will be described. First, the insertion shaft portion 53 of the water discharge member 50 is inserted into the through hole 35 from the seat surface 31 side of the hand-washer 20. The water discharge member 50 is moved until the locking step 55 is seated on the seat surface 31 of the hand-washer 20. As a result, the insertion shaft portion 53 protrudes from the through hole 35 to the back surface 24 side of the hand-washing machine 20.

  FIG. 10A is a bottom cross-sectional view showing a state when the retainer 90 is mounted on the mounted portion 65. The orientation of the retainer 90 is adjusted by the operator so that the mounted portion 65 is positioned between the distal ends of the pair of insertion portions 93. In this figure, the insertion portion 93 of the retainer 90 is disposed to be inclined with respect to the insertion direction P. However, the insertion portion 93 may be disposed substantially parallel to the insertion direction P. In this state, the retainer 90 is moved in the insertion direction P so that the insertion portion 93 is inserted between the opening 42 of the hand-washer 20 and the retaining step portion 81 (not shown in the figure). When the insertion portion 93 is brought into contact with the guide portion 45, the orientation of the insertion portion 93 is guided along the insertion direction P as the retainer 90 is moved.

  FIG. 10B is a diagram illustrating a state after the insertion portion 93 of the stopper 90 is guided by the guide portion 45. When the retainer 90 is guided by the guide portion 45, the claw portions 95 of the pair of insertion portions 93 come into contact with the sliding portion 79 of the mounted portion 65, and the pair of insertion portions 93 widen these gaps. Elastically deforms in the direction. If the retainer 90 is moved in the insertion direction P as it is, the claw portion 95 slides along the sliding portion 79.

  When the protrusion 97 of the retainer 90 is moved until it comes into contact with the sliding portion 79, the contact between the claw portion 95 and the sliding portion 79 is released, and the pair of insertion portions 93 cause these gaps to be removed by elastic repulsion. Deforms in a narrowing direction. As shown in FIG. 7, the retainer 90 is attached to the engagement portions 77 of the attachment portion 65 by engaging the claws 95 of the pair of insertion portions 93 by snap fitting.

  According to the handwashing apparatus 10 according to the above embodiment, the insertion portion 93 can be inserted between the opening 42 of the handwasher 20 and the retaining step portion 41 while adjusting the direction of the retainer 90 by the guide portion 45. Therefore, the retainer 90 can be easily placed at a fixed position, and workability at the time of mounting is improved.

  Fig.11 (a) is bottom sectional drawing which shows a state when mounting | wearing with the retainer 190 to the to-be-mounted part 165 of the hand-washing apparatus as related technology. This hand-washing apparatus has the same configuration and structure as in FIG. 10 except that the guide portion 45 is not provided. In FIG. 11, the components corresponding to the components shown in FIG.

  Consider a case where the retainer 190 is moved in the insertion direction P in a state where the insertion portion 193 of the retainer 190 is inclined with respect to the insertion direction P. In this case, since the orientation of the retainer 190 is not adjusted by the guide portion 45, the pair of insertion portions 193 are elastically deformed to widen the gap as the retainer 190 is moved. As a result, as shown in FIG. 11B, the stopper 190 moves in the insertion direction P to a position where any one of the claw portions 195 of the pair of insertion portions 193 engages with the engaged portion 177. There is a case. In this state, since the other claw portion 195 is not engaged with the engaged portion 177, when the retainer 190 rotates around the insertion shaft portion 153, the retainer 190 is easily detached from the mounted portion 165. End up.

  In this respect, according to the present embodiment, the stopper 90 can be inserted while adjusting the orientation of the retainer 90, so that the claw portions 95 of the pair of insertion portions 93 can be reliably engaged with the engaged portions 77, Workability at the time of mounting becomes good.

  Further, since the tapered portion 46 is formed in the guide portion 45, the distal end portion 93a of the insertion portion 93 of the stopper 90 is inserted between the guide portion 45 and the mounted portion 65 from the entry side in the insertion direction P. It becomes easy to insert, and the workability becomes better.

  Moreover, since the guide part 45 is integrally molded as a part of the hand-washing machine 20, the number of parts can be reduced as compared with the case where the guide part 45 is a separate part, and man-hours and costs required for assembly can be reduced.

  Moreover, the guide part 45 has the following functions. FIG. 12A shows a state where the retainer 90 is attached to the attachment portion 65 from another direction. The orientation of the retainer 90 is adjusted so that the guide portion 45 is positioned in one of the left and right directions X with respect to the pair of insertion portions 93. In this state, when the retainer 90 is moved so that the guide portion 45 enters between the pair of insertion portions 93, as shown in FIG. 12B, the gap between the pair of insertion portions 93 is widened. The base portion 91 comes into contact with the guide portion 45 while being elastically deformed. As a result, the retainer 90 cannot be moved to a position where the claw portions 95 of the pair of insertion portions 93 are engaged with and mounted on the mounted portion 65. Therefore, when the retainer 90 is to be mounted from a direction different from the specific insertion direction P, the movement of the retainer 90 is restricted by the guide portion 45 and cannot be mounted, thereby preventing erroneous assembly.

  Note that the mounting restricting portion 48 also exhibits a similar function. That is, when the retainer 90 is moved so that the attachment restricting portion 48 enters between the pair of insertion portions 93, the base 91 comes into contact with the attachment restricting portion 48. Therefore, it is possible to prevent the erroneous assembly that the movement of the retainer 90 is restricted by the attachment restricting portion 48 and can be attached.

  Further, since a space 49 that allows the movement of the distal end portion 93a of the insertion portion 93 is provided on the distal end side of the insertion shaft portion 53 with respect to the peripheral edge portion 43 of the opening 42, there are the following advantages.

  FIG. 13: shows the bottom sectional drawing of the to-be-attached part 65 of the hand-washing apparatus 10 as a modification. A wall portion 44 is provided on the peripheral edge portion 43 of the opening 42 so as to be continuous with the guide portion 45 and the mounting restriction portion 48. The wall portion 44 is provided on the distal end side of the insertion portion 93. In this case, when the retainer 90 is inserted in the insertion direction P, the tip 93a comes into contact with the wall 44, and the amount of insertion is limited. Therefore, in order to engage the claw portion 95 of the distal end portion 93a of the insertion portion 93 with the engaged portion 77, it is necessary to shift the position of the engaged portion 77 to the side opposite to the insertion direction P. The shape of the mounting portion 65 is limited.

  In this regard, according to the present embodiment, when the retainer 90 is inserted in the insertion direction P, the tip end portion 93a can be disposed up to the space 49 below the peripheral edge portion 43, and the insertion amount can be increased. Therefore, since the position of the engaged portion 77 of the mounted portion 65 is shifted in the insertion direction P, the degree of freedom of the shape of the mounted portion 65 is increased. Moreover, the front-end | tip part 93a of the insertion part 93 can contact the peripheral part 43 of the opening 42, and the fixing degree of the water discharging member 40 by the stopper 90 can be enlarged.

  As mentioned above, although this invention was demonstrated based on embodiment, embodiment only shows the principle and application of this invention. In the embodiment, many modifications and arrangements can be made without departing from the spirit of the present invention defined in the claims.

  Although the hand-washing apparatus 10 demonstrated the example installed in the upper part of the cabinet 110 of the toilet unit 100, the use is not restricted to this, You may be used as a lid | cover of the washing water tank 130. FIG. In addition to the toilet unit 100, the hand-washing apparatus 10 may be used for a washstand or the like.

  The hand-washing device 20 and the water discharging member 50 are not particularly limited with respect to their shapes, and may be formed in a known shape. The seat surface 31 of the hand-washing machine 20 is provided as a part of the bowl surface 23, but may be provided at a position different from the bowl surface 23. The seat surface 31 is provided to be inclined with respect to the horizontal plane, but may be provided in parallel to the horizontal plane. Although the water discharging member 50 demonstrated the example in which the main-body part 51 and the insertion shaft part 53 were comprised by the member of a different body, these may be comprised by the integral single member.
