弾性体の着脱及び交換が可能で容易であり、いつ着脱交
換しても同一位置に設けることが可能である。Since the inner flange portion of the inner hook and the outer flange portion of the outer hook are provided with a recess in one of them so that at least a part of the elastic member projects into the recess, the resistance of the elastic member is increased. As a result, the contact load between flanges that can prevent the inner hook from rotating more reliably is reduced and durability is improved.
The elastic body can be easily attached and detached and exchanged, and it can be provided at the same position regardless of the time of attachment and detachment and exchange.
【００４４】また、構造的な回り止め機構であるため、
弾性体の省化等の心配がない。Since it is a structural detent mechanism,
There is no need to worry about saving the elastic body.
