Claims

[Claims for Utility Model Registration] (1) A pin hole having an opening for pin insertion that opens to the outside is formed in the housing, and the pin hole has:
In the pin inserted into and removably from the pin insertion opening, the pin is contained in the pin hole, and a circumferential groove is formed on the inner peripheral surface of the end of the pin insertion opening side of the pin hole. is formed in the circumferential groove, and a retaining body that comes into contact with the end of the pin to prevent the pin from coming out of the pin hole is removably engaged through elastic deformation, and the retaining body 1. A pin slip-out prevention device, characterized in that it is in the shape of a ring made of an elastic material and is housed in a pin hole. (2) The pin removal prevention device according to claim 1, wherein the removal prevention member is provided with a cut-out portion for taking out the removal prevention member from the circumferential groove. (3) The inner surface of the circumferential groove has an inner tapered surface that is located on the inner end side of the inner surface and is tapered toward the inner side, and an inner tapered surface that is located on the outer end side of the inner surface of the circumferential groove and is tapered toward the outer side. The outer circumferential surface of the pin insertion opening side end of the pin is a tapered surface that is approximately parallel to the outer tapered surface, and the retainer has a cross section that is approximately parallel. a ring-shaped main body that is quadrilateral and is engaged with the circumferential groove and comes into contact with both tapered surfaces of the circumferential groove and the tapered surface of the pin; and a ring-shaped main body that is integrally formed on the inner circumferential surface of the outer end of the main body. 2. The pin retaining device according to claim 1, further comprising a ring-shaped cut-out portion.
