<P>PROBLEM TO BE SOLVED: To provide a simple and inexpensive fastening member and an anticorrosive structure of a joining part including this fastening member, anticorrosive over a long period, and capable of preventing even clearance corrosion. <P>SOLUTION: This anticorrosive structure of the fastening member is composed of a bolt fastened to a fastening object member, a nut threadedly engaged with a screw part of the bolt, a washer fitted between the fastening object member and a head part of the bolt, and a washer fitted to the screw part of the bolt between the fastening object member and the nut. The anticorrosive structure of the fastening member is adopted for fitting an anticorrosive ring composed of a ring-shaped anticorrosive material having the current flowing anodic action and a resin ring arranged on its outer periphery, to a side peripheral surface of the washer fitted to the screw part of the bolt between the fastening object member and the nut, by threadedly engaging a nut-shaped anticorrosive material having the current flowing anodic action with the outside of the nut threadedly engaged with the screw part of the bolt. <P>COPYRIGHT: (C)2008,JPO&INPIT |
