Thus, the water supply pipe 4 and the hand-washing water discharge pipe 3 are generally positioned. When the hand washing water discharge pipe 3 actually approaches the water supply pipe 4, even if the position is slightly displaced, the enlarged diameter part 32 that expands downward from the pipe part 30 of the hand wash water discharge pipe 3 is formed continuously. Have been. For this reason, the connecting part 42 of the water supply pipe 4 is guided to the optimum position while moving from the larger diameter side to the smaller diameter side along the inclination of the inner surface of the enlarged diameter part 32. Then, the connecting portion 42 approaches substantially concentrically with the tube portion 30 and is inserted into the tube portion 30. Since the rib portion is disposed inside the enlarged diameter portion 32, the rib portion moves along the inclination of the enlarged diameter portion 32 and is guided by the rib portion when the position is aligned with the tube portion 30, and the connection portion 42 The upper end is upright.

  Even if the connecting portion 42 is guided by the inclination of the inner surface of the enlarged diameter portion 32 and slightly moves so as to be substantially concentric with the tube portion 30, a square flange portion 43 is arranged around the connecting portion 42, and A gap S <b> 1 is formed between the protrusions 51 a and 51 b and the flange 43. Also, a gap S2 is formed between the claw portion 52 arranged on the outer periphery of the connection portion 42 and the connection portion 42. The connecting portion 42 can move back and forth and right and left within the gap S2 of the claw portion 52, that is, toward the wall surface side of the outer tank 12 and the inner tank 11 side, and also to the right side as shown in FIG. It is possible to move to the left. For this reason, the connection part 42 of the water supply pipe 4 moves so as to absorb a slight positional error when installing the hand-washing bowl 2 in the outer tank 12, and is connected to the hand-washing water discharge pipe 3.
