Claims

[Scope of Claim for Utility Model Registration] (1) A locking screw screwed into each member to be fastened at a predetermined depth, and a thick disc-shaped screw made of a flexible material such as synthetic resin. It consists of a joint body and a socket body fitted onto the joint body so as to be rotatable by a predetermined rotational angle, and the joint body has a dovetail groove into which the head of the locking screw can be engaged in a manner that prevents it from coming out. The fitting groove is opened in the outer circumferential part and is also opened in the bottom surface that abuts the surface of each fastened member, and the outer circumferential part of the joint body is formed in the circumferential side wall of the socket body by its rotation. By pressing the receiving sliding contact part provided on the shaft center side and deforming the joint body, a pressing sliding contact part that can freely hold the locking screw is installed by the gripping edge of the dovetail groove, and A fastening fitting in which a fitting opening is provided at a position that matches the fitting groove opening of the joint body. (2) The receiving sliding contact portion has a deep fitting recess into which the pressing sliding contact portion, which is a protrusion protruding inwardly from the circumferential side wall of the socket body, is fitted, and the fitting recess gradually becomes shallower from the said fitting recess. The fastening fitting according to claim 1, wherein the fastening fitting is formed by a cam groove that is continuous in the circumferential direction. (3) The fastening fitting according to claim (1), wherein the locking screw has a downwardly tapered head at the upper end of the screw rod, and a depth regulating collar formed below the head.
