Therefore, the pulley prevention tool can limit the rotation of the bolt 120 and the nut 140 in the unwinding direction by a simple process of inserting the loosening prevention part 160 on the upper side of the bolt 120.

In more detail, when the bolt 120 is fixed in the state as shown in FIG. 5 and only the nut 140 is to be rotated in the release direction, the release preventing tool due to the coupling of the insertion protrusion 124 and the receiving hole 162. 160 may not be rotated with respect to the bolt (120).

On the contrary, if the nut 140 is fixed and only the bolt 120 is to be rotated in the loosening direction, the loosening prevention part 160 is coupled to the nut 140 due to the coupling between the nut restraining piece 166 and the nut 140. Rotation is impossible.

In addition, since the curved fitting piece 164 maintains a state of being fitted in the curved portion 126, the bolt is held at a constant position unless an upward tension force is applied to the loosening prevention part 160 by the user. The anti-loosening tool 160 from 120 is not separated.

In addition, even if an impact or vibration is transmitted to the nut 140 and the bolt 120 from the outside, as described above, the release preventing portion 160 is fitted to the bolt 120 and the nut 140 at the same time. Therefore, the loosening of the bolt 120 and the nut 140 can be prevented.

The scope of the present invention is not limited to the above-described embodiments, and many other modifications based on the present invention will be possible to those skilled in the art within the scope of the present invention.

In the fastening means provided with the release preventing device according to the present invention, the rotation of the bolt and nut in the loosening direction is limited only by the process of fitting the loosening prevention fitting in the state where the bolt and nut are fastened.

Therefore, the convenience of use of the fastening means is improved, and since the fastening means can prevent collapse of the structure which may be caused by loosening, it is preferable from a safety point of view.

In addition, the anti-loosening tool according to the present invention was composed of a single part.

Therefore, the manufacturing cost is reduced and the price competitiveness is improved.

In addition, the release lock is configured to be selectively detachable from the bolt and nut when it is forcibly tensioned by the user in the state of limiting the rotation of the bolt and nut.

Therefore, there is an advantage that the economic feasibility can be maximized because of the recycling of the release prevention tool.
