な金属製のＥリング４０がある。2. Description of the Related Art Conventionally, a metal E-ring 40 as shown in FIG. 5 has been used as a tightening member for fitting parts such as gears on the shaft member by fitting it on the shaft member.
【０００３】Ｅリング４０は、図６に示す軸部材である

てＥリング４０を外す（図７参照）。The E-ring 40 is used by being fitted in a groove 42 formed in a shaft 41 which is a shaft member shown in FIG.
FIG. 7 is a perspective view showing a state in which the E ring 40 is fitted in the groove 42 of the shaft 41 and the gear 43 passed through the shaft 41 is fixed.
When fitting the E-ring 40 into the groove 42,
2, the opening 46 of the E-ring 40 is abutted, and the top 44 of the E-ring 40 and the lower part 49 of the shaft 41 (see FIG. 7) are strongly sandwiched with pliers or the like, and the opening 46 is expanded while being pressed. The E-ring 40 is held by a special tool and press-fitted into the groove 42. When removing the E-ring 40 from the groove 42, the operator inserts the tip of the minus driver 48 into a gap formed between the notch 47 on the inside of the E-ring and the shaft 41, and rotates the minus driver 48 to make the gap. Remove the E-ring 40 by pushing it apart (see FIG. 7).
【０００４】以上説明したように、Ｅリング４０は簡素
な形状であるため低コストで製造でき、ペンチやマイナ
スドライバ等の比較的一般的な工具で着脱できるため、
事務機等の比較的小型の機械装置で用いられてきた。As described above, since the E-ring 40 has a simple shape, it can be manufactured at a low cost and can be attached and detached with a relatively common tool such as pliers or a flat-blade screwdriver.
It has been used in relatively small mechanical devices such as office machines.
【０００５】[0005]
【発明が解決しようとする課題】しかしながら、上記従

の力を加えられても永久変形し難い緊締部材が必要とさ
れていた。However, the conventional E-ring 40 requires a large amount of force to attach and detach it. For example, when the φ8 axis E ring is attached, 98.
It is necessary to be pressed with a force of about 07 N (10 kgf), and a similar force is required when pulling the E-ring 40 away from the shaft 41 to remove it. Therefore, it cannot be said that the E-ring 40 is easily attached and detached even by using pliers or a flat-blade screwdriver, and it is impossible for an operator to attach and detach it by hand. Therefore, a tightening member having a reduced rigidity is required so that it can be easily attached and detached by hand. In that case, if an excessive force is applied to the outer circumference of the tightening member at the time of mounting, the tightening member may be permanently deformed. Therefore, a tightening member that is easily attached and detached and that is hard to be permanently deformed even when an excessive force is applied to the outer circumference has been required.

The purpose is to prevent the adverse effect on the workability of attaching and detaching the member and to enable reuse.

FIG. 4 shows a tightening member according to the second embodiment of the present invention. The tightening member 10 shown in FIG. 4 is made of metal and has a substantially C shape. This tightening member 10 is formed on the inner ring 12 having an opening 21 that can be inserted into a groove 42 (see FIG. 6) formed in a shaft 41 as a shaft member, and is formed outside the inner ring 12, and near the opening 21. Outer ring 15 connected to inner ring 12
Is equipped with. Further, the tightening member 10 is provided between the inner ring 12 and the outer ring 15 with an engaging portion 16 which is engageable with the tool tip with the tightening member 10 attached to the shaft 41.
In the present embodiment, the engaging portion 16 is provided near the center between the inner ring 12 and the outer ring 15 facing the opening 21.

Is the part that is disengaged from the engaging part 16,
It is provided on both sides of 6. Therefore, when the tightening member 10 according to the present embodiment is attached, even if a load (in the arrow direction in FIG. 2) from the outer ring 15 to the inner ring 12 is applied to the top portion 17 of the tightening member 10, the connecting portion 13 The load is supported. Therefore, similarly to the first embodiment described above, the tightening member 10 is subjected to the force required for mounting (the load described above).
Can be prevented from being permanently deformed, and an adverse effect on the attachment / detachment work due to the permanent deformation of the tightening member 10 can be prevented.

The cutting direction of the slit 11 provided by cutting the inner ring 12 is substantially orthogonal to the direction in which the cutting portion of the inner ring 12 that rotates around the outer ring end portion 18 during attachment moves, that is, toward the outer ring end portion 18. It is the direction to do. Therefore, at the time of mounting, the force of the inner ring 12 attempting to open outward is due to the sliding of the slit 11
5 is not transmitted. That is, the load applied to the outer ring 15 at the time of mounting is not dispersed elsewhere, but concentrated on the end portion 18 of the outer ring 15, so that the force required for mounting can be further reduced as compared with the tightening member 10 according to the first embodiment.
