Claims

[Claims for Utility Model Registration] In an insert bolt engagement fitting that is screwed onto the end of an insert bolt and engages with a dovetail groove of a member to be attached, the opening of the dovetail groove in a first direction perpendicular to the axis The dovetail groove is molded to have a dimension narrower than the width thereof, and when the first direction is aligned with the opening width direction of the dovetail groove and the dovetail groove is entered into the dovetail groove from the opening of the dovetail groove and rotated about the axis. a cylindrical nut body having integrally at its tip an engaging head whose diameter is enlarged in a second direction perpendicular to the first direction so as to engage with each other; is fitted onto the outer circumferential surface of the cylindrical nut main body to allow relative movement in the axial direction and prevent relative rotation;
a pair of overhanging wings protruding on both sides of the engaging head with an overhang interval larger than the opening width of the dovetail groove in the second direction; an annular collar member having a pair of flange surfaces that protrude on both sides of the engaging head at a distance from each other; an elastic member supported by a cylindrical nut body, each of the pair of overhanging wings having a dimension narrower than the opening width of the dovetail groove in the first direction, and a tip of each of the overhanging wings having a width narrower than the opening width of the dovetail groove in the first direction; An insert bolt fastening metal fitting, characterized in that it is located between the flange surface and the distal end surface of the cylindrical nut main body in the axial direction.
