A washer having a bolt head, a nut, and a washer having a bent portion for supporting an unspecified attachment to prevent the bolt from being pulled out from the fastening hole can be formed by inserting a washer larger than the fastening hole into the fastening hole from one side of the plate, And a two-side fastening device.

In the conventional bolt and nut tightening, a normal washer larger than the fastening hole of the valve body is fastened to both sides of the bolt head seat and the nut seat at both sides of the valve body. Therefore, when a washer larger than the fastening hole is inserted into the fastening hole from one side of the valve element, it can not be used as a normal washer.

In order to solve such a problem, Japanese Patent No. 32596 (bolt fastening method and apparatus using split washer), patent No. 33431 (fastening using cutting washer), patent No. 42934 ), Registered utility model No. 54113 (bolt fastening device with lead wire), and utility model registration No. 57012 (socket attachment device with lead wire).

Patent No. 32596 discloses a method in which a circular washer is divided into two halves or more, and a tensile line is connected to each divided washer, and a divided washer is sequentially passed through the fastening holes to be positioned on the opposite side. So that the bolt head is supported, and the bolt is fastened with the nut while preventing the bolt from coming out of the fastening hole. However, since the washer should be cut into two or more halves, even if the nuts are slightly loosened, the divided washers may be separated from the bolts by being widened outwardly. To prevent this, the bolt head is formed with a groove groove, And a complicated bag structure is involved. In addition, since the split washer can be coupled to the position in the case of forming the tensile guide hole in the opposite washer, there is a problem that the manufacturing cost is increased. Japanese Patent No. 33431 discloses a fastener having two or more cutting washers superimposed on each other to form a circular washer larger than the fastening hole, a tensile wire hole penetrating the upper and lower portions of the superposed portion and penetrating the tensile wire, There is a problem in that it is inconvenient to use since the tensile wire must be provided and the cutting washer must be inserted separately and then joined again when it is inserted into the fastening hole. Patent No. 42934 has a variety of advantages due to the unspecified shape of the washer, but it is also necessary to have a tensile line and it is not possible to insert a complete round washer into the insertion hole. In the case of the utility model registration No. 54113 and the utility model registration No. 57012, there may or may not be a tensile line in the cutting washer, and a tensile line is not necessary, but the shape of the cutting washer is a rectangle, There is a problem that it can not be put on the inside of the fastening hole.

SUMMARY OF THE INVENTION In view of the above problems, it is an object of the present invention to provide a washer which not only separates a donut-shaped circular washer into a fastening hole but also has a simple structure even when it is placed on the inner surface of the fastening hole, And it is an object of the present invention to provide a one-side fastening device which is not only a high tension side fastening device but also an insulating or waterproofing device.

A structural feature of the present invention is that a tensile line passing through a center hole of a washer in a washer larger than a valve element fastening hole is prevented from being separated from a central hole and a bent portion folded into a V shape is formed and a bolt connected with a tensile line is inserted into a valve element fastening hole When the washer is folded into the V-shape at the bending portion and then inserted into the fastening hole at the angle and angle that can be inserted into the fastening hole, when the tensile wire is pulled from the outside of the valve body, It is placed evenly inside the fastening hole without being separated and disassembled, and it is caught by the washer of the original state so that only the screw thread of the bolt comes out to the outside of the valve body and fastened with the nut.

The washer having the folded portion can form an unspecified hole, groove, projecting portion, space portion, and additional shape necessary for attaching the attachment, if necessary, for fastening.

The bending part type may be a hinge type, a spring type, a packing type, a tape bonding type, a casing type, an integral type or the like.

The washer having the bending portion is bent or rotated in the V-shape around the bending portion to reduce the size of the washer to a width that can be inserted into the fastening hole, and the effect that the bending portion returns from the inside of the fastening hole to a circular shape larger than the fastening hole. Even if the washer is cut once and divided into a pair of divided washers, it is possible to insert or detach the washer in the shape of a circular washer into a single casing or packing to make one washer again , So that the tensile line can not be detached from the center hole of the washer.
