BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drainage tap device which is attached to the bottom of a sink of a wash basin, for example.

[0002]

2. Description of the Related Art An example of the above-described conventional drainage plug device will be described. An operation section mounted on the upper side of a water tank is operated to move a pin disposed in a drainage pipe mounted on the bottom of the water tank up and down. Thus, the drain cock is moved up and down to open and close the drain port of the drain cylinder, and the hair catcher disposed in the drain cylinder receives hair and the like. Note that the hair catcher and the drain cock are integrally formed.

Therefore, when the operating section is operated to raise the pin, the drain plug rises and the drain port is opened, so that the water in the water tank is discharged from the drain port. When the water is discharged from the drain, the hair catcher provided in the drainage tube receives the hair and the like so as not to clog the water distribution pipe with the hair flowing out together with the water. In addition, when the operating unit is operated to lower the pin, the drain plug is lowered to close the drain port, so that water can be stored in the water tank.
