One of the sides of the side wall portion 342 extending in the longitudinal direction is continuous with the water pipe 32. The width of the side wall portion 342 in the short direction is slightly shorter than the pair of sides 341c of the upper surface 341 and does not extend to the outermost of the pair of sides 341c of the upper surface 341.

The pair of engagement claws 343 are opposed to each other with the gap S (see FIG. 4) between the outer surface of the water pipe 32 and the water pipe 32. The engagement claw 343 hangs from a portion slightly inside from the other side 341 b of the upper surface 341. The engaging claw 343 is formed of an elastically deformable member that bends in a direction approaching or separating from the water pipe 32. The engaging claw 343 is continuous only with the other side 341 b of the upper surface 341, and a side edge along the longitudinal direction of the engaging claw 343 is not connected to the side wall portion 342.
The engagement claw 343 has an engagement protrusion 345 that engages with the engaged portion 251 of the hand basin 2 on the outside of the lower end. The engagement protrusion 345 protrudes outward from the outer surface of the engagement claw 343, and is inclined inward toward the lower end.

  As shown in FIG. 3, the connection pipe 5 has a shape like a three-pronged fork. The connection pipe 5 is provided at a connection portion with the water pipe 32 at the other end of the water supply pipe 4. The connection pipe 5 has a connection pipe-side water supply pipe 51, a flange portion 53, and an insertion portion 52.

  The connection pipe-side water supply pipe 51 is a tubular part that forms a part of the water supply pipe 4 and sends water to the water supply pipe 32 in a state where the connection pipe 5 is attached to the water supply pipe 4. The connection pipe-side water supply pipe 51 has an inner diameter smaller than the inner diameter of the water pipe 32 and is inserted inside the water pipe 32.

  The flange portion 53 is provided on the outer periphery of the connection pipe-side water supply pipe 51.

And a portion 52b extending to the side. The length of the insertion portion 52 is substantially equal to the distance from the released lower surface of the engagement portion 34 to the upper surface 341, that is, the length of the side wall portion 342 in the longitudinal direction.

With reference to FIG. 4, a procedure for attaching the hand-washing spout 3 to the hand-washing bowl 2 will be described.
First, the water pipe 32 is inserted into the insertion hole 25 from above the insertion hole 25 of the hand basin 2. At this time, an engaged portion 251 whose width is partially reduced toward the inside is formed inside the lower side of the insertion hole 25. For this reason, when the water pipe 32 is inserted into the insertion hole 25, the engaging claw 343 of the engaging portion 34 formed on the lower end side of the water pipe 32 is elastically deformed. The engagement protrusion 345 formed at the lower end of the engagement claw 343 slides on the inner wall surface of the insertion hole 25 and is elastically deformed so as to get over the engaged portion 251. 251. Further, since the engagement claw 343 is formed slightly inside (the water pipe 32 side) from the upper surface 341, the other side 341 b of the upper surface 341 contacts the upper end of the engaged portion 251.

  Next, the connection pipe-side water supply pipe 51 constituting the water supply pipe 4 is inserted upward from below the insertion hole 25 of the hand basin 2.

  When the connection pipe-side water supply pipe 51 is pushed toward the water pipe 32, the opposed side wall portions 342 arranged to cover the sides of the gap S between the engagement claw 343 and the water pipe 32, and the water pipe 32. The insertion portion 52 of the connection pipe 5 is inserted into a gap S formed between the outer surface of the connection pipe and the inner surface of the engagement claw 343.

  If there is no connecting pipe 5, the engaging protrusion 345 is provided on the elastically deformable engaging claw 343, so that it is possible that the engaging protrusion 345 is disengaged by an impact applied with some force. However, as shown in FIG. 4, at the same time when the engaging claw 343 gets over the engaged portion 251 and the engaging claw 343 returns to the original state, the insertion portion 52 of the connection pipe 5 is connected to the engaging claw 343 and the water pipe. 32 is inserted into the gap S. The engagement claw 343 does not bend inward due to the insertion portion 52, the position of the engagement claw 343 is maintained, and the release of the engagement is regulated. When the engaging claw 343 of the engaging portion 34 engages with the engaged portion 251 as shown in FIG. 4, the engaging portion 34 of the hand-washing spout 3 removes the hand-washing bowl 2 and does not remove the connecting tube 5 from the back. As long as it doesn't fall off.

According to the present embodiment, the following effects can be obtained.
In the present embodiment, in the connection structure of the hand-washing spout 3 in the hand-washing washing device 1, a tank body 10 having an open upper portion, and a hand-washing basin 2 arranged to cover the opening of the tank body 10 and receiving spout for hand washing. And a water supply pipe 4 for supplying water from the tank body 10 to the hand-washing bowl 2, and a hand-washing water discharge pipe 3 connected to the water supply pipe 4 and discharging water to the hand-washing bowl 2. Further, the hand-washing spout 3 is formed by a spouting head 31 that discharges water toward the hand-washing bowl 2, a water-passing pipe 32 having one end connected to the spouting head 31, and a water pipe 32 formed in the hand-washing bowl 2. And an engaging portion 34 that engages with the joining portion 251.

  According to the present embodiment, the engaging portion 34 of the hand-washing spout 3 is engaged with the engaged portion 251 of the hand-washing bowl 2. By simply inserting it into the insertion hole 25 of the hand-washing bowl 2, the hand-washing spout 3 can be easily constructed and irreversibly fixed.

  According to the present embodiment, the water supply pipe 4 is configured to include the connection pipe 5 that is provided at the connection portion with the water flow pipe 32 and regulates the release of the engagement by the engagement portion 34. Thus, the water supply pipe 4 is disposed below the hand basin 2 with the connection pipe 5, and the release of the engagement is regulated so that the connection pipe 5 maintains the engagement of the engagement portion 34. Once the engaging portion 34 is engaged with the engaged portion 251 of the hand-washing bowl 2, the hand-washing water discharge pipe 3 does not come off. Therefore, the hand-washing spout 3 can be easily and irreversibly fixed.

  According to the present embodiment, the engaging portion 34 has a gap between the outer surface of the water pipe 32 and the engaging claw 343 that is elastically deformable in a direction approaching or separating from the water pipe 32. In addition, the connection pipe 5 includes a pair of insertion portions 52 that are inserted into the gap S between the engagement claw 343 and the outer surface of the water pipe 32. Thus, the pair of engaging claws 343 engage with the engaged portion 251 of the hand-washing bowl 2 by so-called snap-fit, so that the hand-washing spout 3 can be easily connected to the water supply pipe 4. Also, by inserting the insertion portion 52 of the connection pipe 5 into the gap S between the pair of engagement claws 343 and the water pipe 32, the engagement claw 343 is further restricted from being elastically deformed. After the dowel 343 engages with the engaged portion 251, the engagement is prevented from being released. Therefore, the same effects as above can be obtained.

  According to the present embodiment, the engaging portion 34 is configured to further include the side wall portion 342 provided to cover the side of the gap S between the engaging claw 343 and the outer surface of the water pipe 32. Thus, the insertion portion 52 of the connection pipe 5 can be inserted between the side walls 342 that cover the sides of the gap S, and can be guided by the side walls 342 so as to fix the connection pipe 5 at a correct position.

It should be noted that the present invention is not limited to the above-described embodiment, but includes modifications and improvements as long as the object of the present invention can be achieved.
For example, in the above embodiment, the insertion portion 52 of the connection pipe 5 is formed in a rectangular shape having the same width in the vertical direction, but is not limited to this. In order to facilitate insertion of the insertion portion 52 into the gap S between the water pipe 32 and the engagement claw 343, the tip of the insertion portion 52 may be inclined so as to become thinner as it goes.
