<p><P>PROBLEM TO BE SOLVED: To provide an end structure for a water pipe, capable of minimizing the load applied to an end part in diameter enlarging work to a pipe main body to prevent deformation or the like at an end part of the pipe main body, and preventing leak of fluid at the end part of the pipe main body as the pipe main body is connected to a connector, a water pipe provided with the end structure, a connection structure for the water pipe to the connector, and a method for forming the end structure for the water pipe. <P>SOLUTION: This end structure 10 for the water pipe 11 is formed at the end part of the pipe main body 11a of synthetic resin material to prevent leak of fluid at the end part of the pipe main body 11a connected to a joint, and prevent leak of fluid from between the pipe main body 11a and the joint. In the end structure 10 for the water pipe 11, a cylinder body 13 of metal material is inserted into the end part of the pipe main body 11a, and the cylinder body 13 is enlarged from the inner side to form a seal structure between an outer circumferential surface of the cylinder body 13 and an inner circumferential surface of the pipe main body 11a. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
