２４に固定されるものである。(Prior Art) As shown in FIG. 6, a conventional anchor nut has a cylindrical sleeve body 22 with a flange at the upper part in the axial direction via a shear groove 21, and a nut body which also serves as a wedge body at the lower part. 23 is integrally formed, and the base material 24
When a mounting hole 25 consisting of a round hole is provided in the mounting hole 25, the sleeve body 22 is fitted and held in this mounting hole, and an external force is applied to forcibly press the nut body 23 into the sleeve body 22 by wedge fitting. shear groove 2
1 is divided and the nut body is fixed to the base material 24 via the sleeve body.

回転したり緩んだりし易いという問題点がある。(The problem that the invention aims to solve) However, such conventional anchor nuts,
Since the outer periphery of the cylindrical part of the sleeve body is formed into a straight circumferential surface, when it is fitted into the mounting hole of the base material during installation, it is fitted freely and rotates freely until the press-fit is completed. There is a risk of falling off, and there is a problem in that it rotates idly, requiring time and effort to install, and even after installation, it is likely to rotate idly or come loose.

つ迅速な仮止め作業を行うことが困難であつた。 In addition, the plate material on the mounting side is thin, and the cylindrical part of the sleeve body is finished in a severe manner relative to the mounting hole, so if the mating is not done in the proper position, it will bite in the distorted position. It was difficult to perform proper and quick temporary fixing work.

トを提供しようとするものである。 The present invention was developed in view of the above-mentioned problems of the conventional technology, and its purpose is to ensure that the sleeve body is in the correct position and posture when fitting it into the mounting hole of the base material. It can be easily and quickly installed in a temporary manner, and when caulking is performed by tightening the screw after mating, the edges are pushed up to prevent idle rotation and the final tightening work can be carried out quickly and reliably. The purpose of the present invention is to provide an anchor nut that does not rotate idly or loosen even after fastening.

突出変位させてなるものである。(Means for solving the invention) In order to achieve the above object, a cylindrical sleeve body having an annular flange at the upper end, and a nut body having a downwardly expanding conical surface at the lower end of the sleeve body,
In an anchor nut integrally formed with a shear groove in between, the cylindrical portion including the flange of the sleeve body is formed vertically with cut grooves cut at equal intervals on the circumference, and the cut grooves are One of the opposing edges is displaced in the tangential direction from the circumference so that it slips in the forward direction, but stands up when rotated in the reverse direction.
また、スリーブ体の円筒部の上部外周面に、取

うにしながら嵌合すると、スムーズに嵌合し適正
な位置に正しい姿勢で仮止めされる。(Function) When the sleeve body 2 of the anchor nut is fitted into the mounting hole 11 of the base material 10, it is locked by the upper end flange 3. At this time, the sleeve body 2 is fitted while being rotated in the forward direction. Once they are matched, they will fit together smoothly and be temporarily fixed in the correct position and posture.

る為妄りに脱落したり遊動しないようになる。 Once fitted, the edge 6 of the cut groove 5 acts to stand up against the inner circumferential surface of the mounting hole 11 against rotation in the opposite direction, and the inner circumferential surface is given expansion elasticity. They will no longer fall off or move around.

る。(Effects) As described above, the present invention has the sleeve body 2 in which the cylindrical portion 4 including the collar 3 has cut grooves 5 cut at equal intervals on the circumference.
At the same time, one edge 6 of the cut groove 5 that faces each other slips in the forward direction, but when rotated in the reverse direction, it protrudes from the circumferential part in the tangential direction. Therefore, when fitting the anchor nut into the mounting hole of the base material and installing it, the sleeve body can be rotated in the forward direction and pushed in, and it will fit easily, quickly, and effortlessly against the spring pressure. The position is determined, the edge of the cut groove stands out, and temporary fixing can be performed in the proper posture. When screwing the nut body later with a tightening tool or bolt, it is possible to tighten the nut body in the direction in which the screw is tightened. By making the edges of the cut groove stand out, idle rotation can be eliminated and the screw can be tightened strongly and reliably. Able to work efficiently. Moreover, after the caulking is completed, the elasticity of the expansion holding part and the jagged surface on the upper part of the cylindrical part prevents idle rotation and can be expected to have an effect of preventing loosening.
