Affected by. However, according to the present invention, since the mounting of the seal member 6 on the valve body 5 is displaceable in all directions within the mounting surface and in the direction orthogonal to the mounting surface, the sealing member 6 has the above shape accuracy. Also, the valve body 5 is displaced so as to absorb the error in the relative posture between the valve body 5 and the drainage port 20 due to the influence of the assembly precision, and in the closed state shown in FIG. Therefore, during drainage of stored water that is performed by removing the drain tank 3,
The closed state of the drainage port 20 can be maintained well, the drain water can be prevented from leaking from the drainage port 20, and the contamination of the peripheral portion can be prevented.

Further, in the above embodiment, the support plate 55 of the valve body 5 is loosely fitted to the support shaft 22, and the valve body 5 can change its posture within the range of the loose fitting gap. Can

It is possible to reliably prevent the generation of dirt around the area due to water leakage.

Further, since the pivot shaft of the valve body is loosely fitted to the support portion and can be displaced within this loose fitting gap, the influence of the shape and positional accuracy of the valve body and the drainage port is influenced by the seal member. It is possible to absorb the displacement of the valve body itself as well as the displacement of the valve body so that the sealing member can be firmly attached to the drain port to achieve a good closed state, and the drain tank is removed to drain the stored drain water. In this case, there is no risk that the surroundings will be contaminated due to water leakage from the drain pan.

Further, since a water stop rim rising from the pressing surface to the drainage port is provided on the periphery of the seal member, the drain water flowing out from the drainage port when the valve body is opened is stopped,
The present invention has an excellent effect such that it can be surely collected by guiding it to a predetermined position on the drain tank, and it is possible to prevent the surrounding dirt from being generated by the drain water.
