Abstract

An outer member, an inner member, and an inside fixing member overlap each other and fastened together by a fastening member. The outer member is made of fiber reinforced resin, and fibers contained in the fiber reinforced resin-made outer member are arranged in a direction crossing the above-described overlapping direction. A bolt of the fastening member comprises a conical (truncated cone-shaped) middle portion which is poisoned between a head portion and a shaft portion. In a case where the outer member and the bolt are offset from each other in a radial direction of a through hole of the outer member, the conical middle portion partially contacts an edge portion of the through hole and compress a contacted portion of the outer member in the overlapping direction.

Dependent claims

A fastening structure of a fiber reinforced resin-made member, comprising:

a fiber reinforced resin-made member;
another member overlapping with the fiber reinforced resin-made member;
and
a fastening member fastening the fiber reinforced resin-made member and the other member,
wherein said fiber reinforced resin-made member has a through hole penetrating in a first direction which corresponds to a direction of said overlapping and contains fibers which are arranged in a direction crossing said first direction,
said other member has a hole portion which is continuous to the through hole of said fiber reinforced resin-made member,
said fastening member is inserted into the through hole of said fiber reinforced resin-made member and the hole portion of said other member so as to fasten the fiber reinforced resin-made member and the other member, and the fastening member comprises a compression portion which is configured to partially contact an edge portion of the through hole of said fiber reinforced resin-made member in a case where the fastening member is offset from the fiber reinforced resin-made member and compress a contacted portion of said fiber reinforced resin-made member in said first direction.

A fastening structure of a fiber reinforced resin-made member, comprising:

a fiber reinforced resin-made member;
another member overlapping with the fiber reinforced resin-made member and configured to have larger rigidity than the fiber reinforced resin-made member;
and
a fastening member fastening the fiber reinforced resin-made member and the other member,
wherein said fiber reinforced resin-made member has a through hole penetrating in a first direction which corresponds to a direction of said overlapping and contains fibers which are arranged in a direction crossing said first direction, and
said other member has a hole portion which is continuous to the through hole of said fiber reinforced resin-made member, and the other member comprises a compression portion which is configured to partially contact an edge portion of the through hole of said fiber reinforced resin-made member in a case where the fastening member is offset from the fiber reinforced resin-made member and compress a contacted portion of said fiber reinforced resin-made member in said first direction.
