[0003] As such an attachment for hanging bolts,
For example, there is one shown in FIG.
No. 13). The attachment 1 is urged in the direction of the engagement head 2 by a spring 4 against a cylindrical nut body 3 provided with an engagement head 2 having a vertical dimension smaller than the width dimension of the dovetail groove and a wide lateral dimension. The annular flange member 5 is fitted. When the engaging head 2 protrudes into the dovetail groove and is engaged by being rotated substantially at a right angle, the overhanging wings 6 of the annular flange member 5 fall into the dovetail groove and rotate the cylindrical nut body 3 and the engaging head 2. Regulate movement. At the same time, the flange portion of the engagement head 2 and the flange surface 7 of the annular flange member 5 sandwich both green portions of the dovetail groove by the urging force of the spring 4. When a suspension bolt is screwed into the cylindrical nut body 3 from below and the tip of the suspension bolt is strongly pressed against the inner wall of the dovetail groove, the engaging head 2 is pressed against the inside of the dovetail groove by the skin force.

[0004] However, in such a hanging bolt attachment 1, the annular flange member 5 needs to be formed in a cylindrical shape so that the relative movement in the axial direction is possible and the relative rotation is prevented. It is necessary to provide a ridge 8 on the nut body 3 and provide a notch 9 for engaging with the ridge 8 on the annular flange member 5.
The mechanism becomes complicated and the manufacturing cost increases. Further, a spring 4 is used to bias the annular flange member 5 in the direction of the engaging head 2, and a spring support 10 is further attached to the cylindrical nut body 3 to support the spring 4. And the number of parts is large and the number of assembling steps is increased, so that the manufacturing cost is further increased. Parts other than the cylindrical nut body 3, that is, the annular flange member 5, the spring 4, the spring support 10, and the like are necessary only when the hanging bolt engaging metal fitting 1 is engaged with the dovetail groove. It was pointed out that the uneconomical property was unnecessary after being engaged.
