。[Claims for Utility Model Registration] 1. A socket part 11 of a rigid tube, an insertion part 12 of a soft pipe inserted into the socket part, and a gap between the socket part 11 and the insertion part 12. In the joint portion consisting of the annular packing 13 to be inserted, a tapered surface 111a is provided on the inner surface of the socket portion 11 of the rigid tube in the direction of the outer end, and the valve portion 132 made of soft rubber at the front and the hard rubber at the rear are connected to each other. A heel portion 131 is formed integrally with the heel portion 131, and a tapered surface 1 of the socket portion is formed at the rear end of the heel portion 131.
The packing 13 having a tapered surface 131a corresponding to the tapered surface 131a corresponding to the tapered surface 131a is inserted into the socket 11 and inserted into both the tapered surfaces 11.
A structure for preventing packing from being pulled out at a joint between a rigid tube and a soft tube, characterized in that la and 131a are slidably abutted against each other. 2. The valve portion 132 of the packing 13 has sufficient material to fill the gap created in the joint within the allowable deformation range of the insertion portion 12 of the soft tube.Claim 1 of the Utility Model Registration Claim A structure that prevents the packing from being pulled out at the joint between a rigid pipe and a soft pipe as described in . 3 The valve part 132 of the packing 13 has a tongue piece 132a.
. 4. The tapered surface 111a of the socket portion 11 is a joint portion between a rigid tube and a soft tube according to any one of claims 1 to 3 of the utility model registration claims, which is formed in an inner circumferential groove 111 having a flange 112. Structure to prevent packing from being pulled out. 5. A structure for preventing packing from being pulled out at a joint between a rigid pipe and a soft pipe according to any one of claims 1 to 4 of the registered utility model, wherein the rigid pipe is a sleeve joint.
