ルギヤ（３）に噛合わせる位置に設計し 取り付ける。[Detailed description of the invention] Conventionally, bolts (or nuts) were generally tightened by directly tightening the bolt head (or nut) with a tool such as a spanner, but this required force and was difficult to recover. As for the stop, even after various efforts were made, it was not perfect. The present invention provides an oval-shaped flange on the periphery of the bolt head (or nut), cuts a wheel gear on the periphery, and tightens the worm gear attached to the washer side by hand or with a tool, thereby easily increasing the tightening force. The head is a circular bolt (1) with a tin-shaped flange (2) on the circumference, and the head is provided with a tin-shaped flange (2) on the circumference of the bolt (1), and the bolt (1) has a circular head. Shape of E, Eel gear (3
), stand up the bearing part (6) (6) on the outward protruding part (5) of the washer (4), and insert the shaft hole (7) into this.

見ない。A textured surface (11) is provided on the back side of the washer (4) by press forging or the like to prevent the washer (4) from rotating. Assuming that the bolts are now inserted and fixed, the bolts (1) and washers (4) should be pressed against the frame plate surface (12) until the back of the bolt heads press against the washers (4).
) are screwed together in advance, and from the pressing position until the final tightening, screw in the wing part (9) or the hexagonal hole (1
0), etc. manually or with a tool, the uneven surface (11) on the back of the washer (4) digs into the frame plate surface (12) as the bolt (1) rotates, causing the washer (
4) does not rotate, but when the wheel gear (3) on the bolt head is rotated by the worm gear (8), the head rotates smoothly on the upper surface of the washer, exerting more and more pressing force on the washer (4), and at that gear ratio. It has high torque and also serves as a detent mechanism. Furthermore, if necessary, use a retaining plug (13) with a leaf spring that can fit into the hexagonal hole (10) of the worm gear (8).
It will be safer if a light load detent is applied. In addition, when tightening nuts, if the design is the same as the bolt head, the washers can be tightened with the same specifications. As described above, the present invention uses a worm wheel mechanism to increase the tightening force by reducing the gear ratio and also has a detent effect, so it is possible to use a low-torque manual tightening mechanism, a light-load detent mechanism, and also to reduce the bolt head. It is also possible to position the worm gear attachment part in any space of the part, and it can also be used in narrow tightening spaces. In addition, if the molded with foil gear (14) is used as an attachment, it can be used for general purposes such as conventional bolts.
It can also be configured as a closed type as shown in Fig. 4, and can be conveniently used at the place where it is placed. If the wheel gear is made by cutting out an approximate tooth profile, the cost will be low. It is unique in that it uses a worm mechanism to tighten the bolts to secure the washers.

る締め付けボルト。A wheel gear is cut around the periphery of the bolt head (or nut), and the worm gear that meshes with it is supported by a washer with a textured back surface that protrudes outward, allowing the worm gear to rotate at low torque. By moving the washer, the bolt (or nut) is screwed in with high torque, and the tightening force of the bolt screw crimps and fixes the uneven surface on the back of the washer to the frame plate surface when creating a detent mechanism. A tightening bolt using a worm gear.
