Since the longitudinal direction of 52 remains in the horizontal direction of the outer wire 12 orthogonal to the center line of the drain port, it is possible to maintain the waterproofness adjusted at the time of attachment. The support or holder stay 52 supporting the end of the out-wire 12 is attached to the drain hole main body 44.
Since the length of the drain plug 71 can be made constant, the water stop position and the drain position of the drain plug 71 with respect to the drain port can be set without adjusting the expected position.

The above-described embodiment has a structure corresponding to claim 3. However, if the stay ring 51 and the holder stay 52 are formed as one component, the structure corresponds to claim 1, and the holder The stay 52 is connected to the drain hole main body 44.
When attached directly to the device, the configuration according to claim 2 is obtained, and a corresponding effect can be obtained similarly. In the case of the configuration of claim 1, the guide portion 41g, the engagement concave portion 51g, and the engagement portion 51u may be omitted.

In the case of the first aspect, since the support does not have to be rotatable with respect to the drain hole main body 44, the engaging portion provided on the drain hole main body 44 and the engaging claw 5 provided on the support body are not required.
1n may be other embodiments. Next, in the case of the configuration of claim 2, the locking portion of the drain hole main body 44 may be a substantially circumferentially concave portion, and the engaging portion of the holder stay 52 may be a holding claw 52c that rotatably engages with the concave portion. It is.

In the case of the configuration of claim 3, since the holder stay 52 does not need to rotate in the circumferential direction with respect to the stay ring 51, another mounting method may be used. In addition,
Although the description has been given of the example of the drainage tap device of the wash basin, it goes without saying that the present invention can be applied to other things such as a bathtub in which the drainage tap is moved up and down by remote control.

[0053]

As described above, according to the first aspect of the present invention, the support can be attached to the drain hole main body with one touch so as not to fall out of the drain cylinder. And, since the supporting body supporting the end of the out wire is configured to be attached to the drain hole main body, the length from the drain port to the pin can be made constant, so that the position of the drain plug with respect to the drain port can be fixed. The drainage position can be set without adjusting to the expected position.

Next, according to the invention of claim 2, according to claim 1
In addition to the same effects as described above, the holder can be attached to the drain hole main body with one touch. Then, since the holder is formed in an I-shape in plan view and attached to the drainage tube, a sufficient flow path can be secured on both sides of the holder, and good drainage can be ensured.

Further, since the holder can be rotated with respect to the drain hole main body, the longitudinal direction of the holder can be directed in the horizontal direction of the outer wire orthogonal to the center line of the drain port regardless of the thickness of the water tank. Since the holder does not tilt with respect to the drain hole main body due to the reaction force of the inner wire and the outer wire trying to return to a straight line, the drain port is moved up and down in the direction of the center line of the drain port via the pin to secure the drain port. It is possible to secure the water stoppage by setting the water stop state.

Next, according to the invention of claim 3, claim 1
Or, in addition to the same effect as in claim 2, or because the support is configured not to rotate in the circumferential direction of the drain in the drain cylinder, the support does not rotate due to aging, and the longitudinal direction of the holder is in the drain. Since the outer wire remains oriented in the horizontal direction perpendicular to the center line of the outer wire, the water stoppage adjusted at the time of mounting can be maintained.
