<p><P>PROBLEM TO BE SOLVED: To provide a connecting method and a connecting structure, which prevent even a flexible drain pipe having a large hole diameter and a recessed groove in the outer peripheral surface from being dropped out of a pipe joint. <P>SOLUTION: The connecting structure 1 of the drain pipe includes the drain pipe 2 having the recessed groove 21, a drop-out prevention member 3 fitted to the recessed groove 21 of the drain pipe 2, and the pipe joint 4 externally fitted to the drain pipe 2 to which the drop-out prevention member 3 is fitted (hereinafter referred to as "a drain pipe 22 already fitted"). The first process for fitting the drop-out prevention member 3 made of a synthetic resin to the recessed groove 21 of the drain pipe 2 and the second process for pressing the pipe joint 4 into the drain pipe 22 already fitted and adhering the inner peripheral surface of the pipe joint 4 to the outer peripheral surface of the drop-out prevention member 3 after an adhesive agent 7 is applied to the outer peripheral surface of the drop-out prevention member 3 and the inner peripheral surface of the pipe joint 4 are performed in sequence. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
