<p><P>PROBLEM TO BE SOLVED: To provide a pipe joint which eliminates use of an adhesive in connection between a pipe body to be connected and a hard-resin made pipe joint, and also, capable of constituting a connection structure excellent in adhesion in-between the pipe body. <P>SOLUTION: A soft layer made of a soft material is formed on at least the inner peripheral face of at least one connection end part of a joint body formed of a hard material. The whole part from the inner peripheral face to the outer peripheral face of the one connection end part is formed of a soft layer. A single or a plurality of thin-walled parts are formed to the connection end part along in the axial direction. The pipe body to be connected is connected by fastening the outer periphery of the connection end part with a fastening member. The joint body made of a hard resin and the soft layer made of a soft resin are formed by fusing integrally with each other by injection molding. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
