<p><P>PROBLEM TO BE SOLVED: To provide a relief valve with a resin body, solving a problem in which resin cracking may occur with a machine screw hole existing in the resin body to be fixed to an exterior body. <P>SOLUTION: No mounting machine screw hole exists in the resin body, a plate having a different material from the resin body is incorporated as another component, and a machine screw hole is formed in the plate. This construction avoids issues and concerns which may be caused by the machine screw hole existing in the resin body, reduces cost with a material for the body changed from metal into resin, reduces the mass, and gives no troubles to a production plan with great changes of raw material cost. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
