The upper shaft 31 having a predetermined diameter is extended to the bottom, and the external thread 31a is formed on the outer peripheral surface of the lower end of the upper shaft 31.

In addition, the lower shaft 32 having the same diameter as the upper shaft 31 is mounted to the lower portion of the upper shaft 31, the rack gear 32a of a predetermined width is formed on the outer peripheral surface of the lower end of the lower shaft 32 Is formed.

2 and 4, the drain valve pressing pressure adjusting means is screwed to the upper shaft 31 through a female screw 36a formed on the inner circumferential surface of the housing 36 having a hollow pipe shape. The T-shaped protrusion 32b protruding from the upper end of the lower shaft 32 is accommodated in the housing 36, and a spring 35 through which the 'T' shaped protrusion 32b penetrates is built in the housing.

In addition, the drainage pipe 20 is divided into an upper drainage pipe 22 and a lower drainage pipe 23 and connected to each other by screwing, and the upper and lower shafts 31 and 32 are installed upright through the inside thereof. However, the upper and lower shafts (31, 32) are supported through three celebration housings (34a, 34b, 34c).

The celebratory housings 34a, 34b, and 34c have a ring shape, and the upper celebratory housing 34a and the central celebratory housing 34b are disposed at the engaging jaws 22a, 23a of the upper drain pipe 22 and the lower drain pipe 23, respectively. It is supported, and the lower shaft housing 34c is screwed to the inner circumferential surface of the lower drain pipe 23 through a screw portion formed on the outer circumferential surface.
