あつた。(Problem to be solved by the invention) In the first conventional example above, the packing 55 is
Moreover, the small diameter portion 57 of the packing 55 requires a thicker wall thickness than the large diameter portion 56 in order to be fitted and fixed to the flange 54 of the body portion 51. Since it has poor elasticity, if the tip A' of the drain hose A is press-fitted into this, the gasket 55 will easily fall off from the body 51 as the drain hose A is inserted and removed. There was a problem.

A groove 68 is formed in a vertically symmetrical position with the lower convex peripheral edge 67, into which a part of the guide ring 64 is fitted and overlapped, so that when the cable 60 is inserted or removed, unbalanced external pressure is applied to the supporting part of the packing. However, since the tip 69 of the packing is somewhat thick, only this thick tip 69 hits the outer periphery of the inserted cable, and the packing is easily damaged. There was a problem that airtightness could not be achieved.
