REVERSE ROTATION PREVENTION STRUCTURE FOR FASTENING PART
Document Type and Number:
WIPO Patent Application WO/2015/050043
Kind Code:
A1
Abstract:
The present invention is provided with a fastening part and an interposition member, and when a member to be fastened is fastened, a fastening part-side seat part is formed in a male fastener, and a fastening part-facing part and a member-facing part are formed on the interposition member side. A first engagement mechanism (A) is formed between the fastening part-facing part and the fastening part-side seat part, and when at least the fastening part-side seat part tries to rotate in the direction in which the male faster in a fastened state is loosened, the fastening part-facing part and the fastening part-side seat part are engaged with each other to thereby prevent the relative rotations thereof. The interposition member is simultaneously engaged with a plurality of fastening parts that are fastened to the member to be fastened, thereby configuring a second engagement mechanism (B) in which even if rotational force in a specific direction acts on the interposition member, the relative rotations of the interposition member and the member to be fastened are prevented. Looseness between the male fastener and the member to be fastened is prevented by the actions of these first engagement mechanism (A) and second engagement mechanism (B).
