[0002]

2. Description of the Related Art When a drain bowl is provided in a conventional wash bowl, a structure as shown in FIGS. 3 and 4 has been adopted. A drainage tube 3 is inserted from the top into a through hole 2 provided at the bottom of the basin 1, and a lock nut 4 is screwed onto the outer periphery of the drainage tube 3 below the through hole 2 to insert the drainage tube 3 into the through hole 2. A drain plug member 6 is provided inside a drain port 5 in the drain pipe 3.
The drain plug member 6 is provided with a hair catcher 8 at an upper end of a cylindrical shaft 7 and a guide member 9 at a lower end of the cylindrical shaft 7 as shown in FIG. A plug 11 for inserting and closing the upper end opening of the drain port 5 is fixed to the upper end of the operating shaft 10 and a weight 12 is attached to the lower end of the operating shaft 10. The outer periphery of the hair catcher 8 is provided with the drain plug 3 with the drain plug member 6 provided inside the drain port 5.
, And the outer periphery of the guide member 9 is placed on the step 13 on the inner surface of the drainage tube 3. A drain pipe 14 is led out from the drain pipe 3 to the side, and a lid 15 is screwed to a lower end of the drain pipe 3. One end of the release wire 16 is attached to the lid 15, and the release wire 16
The mounting portion 17 provided at the other end of the device can be mounted on a counter or the like. The release wire 16 is formed by slidably inserting the inner wire 16b through the outer tube 16a, and the knob 18 provided at the end of the inner wire 16b is operated on the mounting portion 17 side to slide the inner wire 16b. I can do it. The end of the inner wire 16 b is projected upward from the lid 15, and the inner wire 16 b is located at the center of the drainage tube 3, and the upper end of the inner wire 16 b contacts the flat lower surface of the weight 12. It is. When the knob 18 is pushed downward, the lower surface of the weight 12 is pushed at the end of the inner wire 16b in the drainage tube 3, the operating shaft 10 slides upward, and the plug 11 moves upward. As a result, the drain port 5 is opened, and water flows as shown by the arrow in FIG. When the knob 18 is pulled upward, the end of the inner wire 16b in the drainage cylinder 3 is lowered,
The stopper 11 moves down together with the operating shaft 10 by the weight of the weight 12, and the opening at the upper end of the drain port 5 is closed by the stopper 11.

In the prior art, the stopper 11 is supported horizontally in the open state by bringing the outer periphery of the hair catcher 8 into contact with the inner surface of the drainage tube 3. However, in order that the operating shaft 10 slides up and down smoothly and the plug 11 opens and closes smoothly, a structure is adopted in which a gap S is provided between the inner surface of the drainage tube 3 and the outer periphery of the guide member 9. I have. However, in the above conventional example, the end of the inner wire 16b is only in contact with the flat lower surface of the weight 12, so that when the plug 11 is open, the gap S causes the operating shaft 10 and the plug 11 to move in the horizontal direction. Rattling occurs. Due to this rattling, there is a problem that the plug body 11 rattles and generates abnormal noise when water is drained. Further, when the drain plug member 6 is pulled out upward and removed for cleaning the hair catcher 8 or the like, the plug 11 is not located at the center, so that there is a problem that it is difficult to grasp the plug 11.

SUMMARY OF THE INVENTION The present invention has been made in view of the above description, and has as its object to eliminate rattling of a plug body in a horizontal direction so that abnormal noise is not generated at the time of drainage.
