している。Now, the front shape of the drainage port (10) in this embodiment is
As shown in FIG. 2, both sides were vertically extended upward from both ends of the lower side (10a) of a predetermined length, and both ends of the both sides were connected by an arc. Then, as shown in FIG. 1, the vicinity of the upper surface of the base portion (11) with which the lower side (10a) coincides is formed slightly lower, and the base portion is formed from the peripheral portions of the both sides of the drainage port (10). A pair of drainage guide ribs (17) (17) formed around the outer peripheral edge of (11)
The drain groove (16) is also formed by digging so that the upper surface of the base portion (11) in between also corresponds to the depth of the lower side (10a).
言い換えれば、排水溝（16）のうち、筒部（12）との交
叉部分が排水口（10）の下辺（10a）となるのである。In other words, the intersection of the drain groove (16) with the tubular portion (12) becomes the lower side (10a) of the drain port (10).

一層、ブッシュ（１）内の排水機能が向上することとな
る。Thus, the drainage port (10) on the upper surface of the base (11)
Since the vicinity of the lower side (10a) is formed lower than the others, water or hot water that has entered the cylindrical portion (12) of the bush (1) will be collected near the lower side (10a) of the drainage port (10), and as it is. Since the water is drained to the outside through the drain groove (16) formed following the lower side (10a), the drainage function in the bush (1) is further improved.

ッシュ（１）に実施しても良いことは言うまでもない。Since this embodiment is a device for improving the drainage port (10) of the bush (1), the fitting relationship with the operating knob (6) and the canopy (3) is the same as the conventional one. Therefore, even if it is desired to improve the waterproof performance of the conventional bush (1), only the bush (1) needs to be replaced with that of the present invention. In addition, although this embodiment is applied to the operation knob in the water heater of the balanced-flue type bath kettle, it may be applied to the bush (1) of another operation knob that may cause water intrusion. Not to mention good things.
