立て方である。(Operation) Next, the operation of the present invention will be explained. To assemble the cover a of the present invention to cover the existing nut 1,
As shown in the drawing, the entire outer surface of the nut 1 is covered with a cover a. As a result, the two are fitted together as shown in the drawings. Then, the flange 5 of the cover a is pushed into the groove 15 of the washer b, and the flange 5 is fitted.
With the above steps, assembly is completed. The above is how to assemble the cover a and the washer b to the nut 1. Next, the head of the bolt 2 is covered with a cover a and a washer b, and in order to assemble the bolt 3, the cover a is applied to the entire outer surface of the head 9 of the bolt 3. The entire outer surface of the head 9 is closely covered. Then, the male screw part 13 of the washer b is inserted into the insertion hole 14 and lifted upward, and the flange part 5 is pushed into the groove part 15 to fit the flange part 5. The above is how to assemble cover a and washers b.

ことができた。(Effects) (1) The present invention is as described above, and is a cover that closely covers the entire outer surface except for the bottom surface, and the side surface of the cover is the same as the side surface of the nut and bolt head. In particular, the flange part protruding outward from the lower part of the cover part is loosely fitted into the groove part formed on the inner surface of the washer part, and the back part of the washer part is fitted inwardly. Because it is curved, even if the cover covering the nut or bolt head rotates,
The washer does not rotate in proportion to this rotation, and no significant frictional resistance is generated between the cover and the washer or between the washer and the facing surface of the object to be tightened. Therefore, compared to conventional nuts and bolt head covers, tightening is much easier, and tightening work efficiency can be significantly increased.
