<P>PROBLEM TO BE SOLVED: To provide a connection part of drainage piping in which a body to be connected is easily connected to a connection body without using an adhesive, a retaining member is protected, and versatility of members is high. <P>SOLUTION: The connection part of the drainage piping for connecting the drainage piping comprises: the connection body including a connection cylinder part 2 provided with a groove part 2a along a circumference; the body to be connected including an inward flange part 4 to be attached to the connection body; and a retaining member 6 for locking the body to be connected to the connection body. The retaining member 6 is arranged at the groove part 2a, is elastic in a circumferential direction of the connection cylinder part 2, is at least partially projected from an inner peripheral edge of the inward flange part 4 in a state with no stress, and is housed in the groove part 2a to settle the entire outer periphery inside the inner peripheral edge of the inward flange part 4 when the stress is applied in the inner peripheral direction of the connection cylinder part 2. <P>COPYRIGHT: (C)2013,JPO&INPIT |
