される。 Next, the legs 14, 14 of the fastener T are fitted into the insertion hole 10. Thereafter, while pressing the presser jig J against the protrusion 15, the fastener T is pushed in. As a result, the entire leg piece 14 is bent downward, and at the same time, both the leg pieces 14, 14 are inserted into the insertion hole 10 while being mutually compressed and deformed. however,
The amount of deflection of the entire leg piece 14 in the axial direction is regulated by the presser jig J being brought into contact with the left and right side edges of the upper surface of the pressing piece 13 (see FIG. 4A). and,
With both pressing surfaces 16, 16 of the fastener T in contact with the support piece 7 of the operating lever 3, both leg pieces 14, 14 are elastically returned in the expansion direction, but the entire leg piece 14 is bent downward. Therefore, both biting edges 19, 19 are located below the corresponding engaging edges 12 (see FIG. 4B). Thereafter, when the pressing by the presser jig J is released, the entire leg piece 14 is elastically returned upward, so that both biting edges 19 are engaged with the engaging edges 12, respectively (see FIG. 4C). . Thus, the work of tightening the pivot point of the operating lever 3 is completed.
次に、本例留め具Ｔの効果について述べる。 Next, the effects of the fastener T of this example will be described.
操作レバー３における回動支点に対しほぼ一

内に限定されているからである。したがつて、
従来と異なり、留め具Ｔの押し付け力の強弱に
よつて操作レバー３の操作性あるいはがた付き
の発生が回避されるのである。 In other words, the clamping force against the rotation fulcrum is
6 is a force that presses the support piece 7, and this is due to the elastic restoring force of the leg piece 14 as a whole. This elastic restoring force is determined by the amount of deflection of the entire leg piece 14, and in this example, this is limited within the range of the amount of protrusion of the protruding piece 15. Therefore,
Unlike the conventional case, the operability of the operating lever 3 or the occurrence of wobbling can be avoided by changing the strength of the pressing force of the fastener T.
留め具Ｔの板脱が強固に規制される。何故な

パー面とされているからであり、また、このた
め留め具Ｔに抜け方向の外力が作用された場
合、この外力が両脚片１４，１４が拡開させる
方向への力として作用するからである。 The plate detachment of the fastener T is strongly regulated. This is because both the engaging edge 12 and the biting edge 19 are tapered surfaces, and therefore, when an external force is applied to the fastener T in the direction of removal, this external force is applied to both leg pieces 14, 14. This is because it acts as a force in the direction of expansion.
操作レバー３のがた付きが防止される。 Shaking of the operating lever 3 is prevented.
即ち、留め具Ｔの軸方向へのがた付きに関し
ては、上記した締着力により規制され、軸と直
向する方向については、両がた付き防止片２
１，２１によつてそれぞれ規制されるからであ
る。 That is, the rattling of the fastener T in the axial direction is regulated by the above-mentioned tightening force, and in the direction perpendicular to the shaft, both rattling prevention pieces 2
This is because they are regulated by 1 and 21, respectively.
