Next, the second member 61 is stacked on the front surface of the first member 51, and the bolt hole 62 is made to correspond to the screw hole 21 a of the cage nut 1. When the bolt 71 is screwed into the screw hole 21 a through the bolt hole 62, the nut member 2 rotates with the bolt 71. As shown in FIG. 6 (B), the nut member 2 stops at a position where the engagement recess 21c on the side face abuts against the holding piece 32 of the cage member 3 and the inner edges 32d and 33d of the press-fitting piece 33, and thereafter The tightening of the bolt 71 proceeds. In this state, the four corners 21 b of the head portion 21 of the nut member 2 project to the rear surface side of the hole edge of the mounting hole 52, and the cage nut 1 is prevented from coming forward with respect to the mounting hole 52 of the first member 51. When the bolt 71 is tightened to a predetermined torque, the second member 61 is fixed to the front surface of the first member 51 in the state shown in FIG.

係合凹部21cは、ヘッド部21の側面が縁部32d,33dに圧接されるときの押圧角度を可及的に直角に近づけて、保持片32と圧入片33を外側へ広げる作用を防止する。ヘッド部21の各側面は、係合凹部21cを境に、各遊動間隔部36に対応する側が、支持片35の厚み分だけ他側より外方へ大きく突出している。これにより、ナット部材2が作用位置にあるときの四隅部2bの突出寸法を大きくし、取り付け孔52の孔縁との係合面積を大きくとれるようにしてある。   The engagement recess 21c prevents the action of spreading the holding piece 32 and the press-fitting piece 33 outward by bringing the pressing angle when the side surface of the head part 21 is pressed into contact with the edges 32d and 33d as close as possible to a right angle. . Each side surface of the head portion 21 protrudes more outward than the other side by the thickness of the support piece 35 on the side corresponding to each floating interval portion 36 with the engaging recess 21c as a boundary. As a result, the protruding dimensions of the four corners 2b when the nut member 2 is in the operating position are increased, and the engagement area with the hole edge of the attachment hole 52 can be increased.
