(12) is a joint member, which is a cylindrical member having an outer diameter and a desired length that can be inserted into the hole (11). Joint member (12)
An insertion hole (13) for inserting the shaft (10) is formed in the shaft. The joint member (12) and the shaft (10) or the hole (11) are connected in a detented state by a key (14) and a key groove (15), respectively.

る。In the joint member (12), slits (16) and (17) extending in the axial direction from the end of the member are formed on the same plane from both ends of the member. 17) is the member (1
In the center part of 2), the terminal ends without being continuous, and a discontinuous part (18) is formed between both slits. A second slit formed on the side where the insertion hole (13) for inserting the shaft (10) is formed
On both sides of (17), bolts (19) capable of expanding and contracting the width of the second slit (17) are screwed at positions deviated outward from the insertion holes (13). By tightening the bolt (19), the width of the second slit (17) can be reduced, and the play between the second slit (17) and the shaft (10) inserted into the insertion hole (13) disappears. At the same time, the width of the second slit is reduced, so that the lever (11)
The width of the first slit (16) formed on the side is increased,
Since the outer diameter of the joint member (12) inserted in (11) is enlarged, the play between the joint member (12) and the hole (11) also disappears.

ことが可能となる。Since both slits (16) and (17) extend almost to the center of the joint member (12), an impact force or excessive rotation from the rotating shaft (10) or the hole (11) side is obtained. When a force is applied, the joint member (12) exhibits flexibility in the discontinuous part and can absorb such a force, preventing damage to the equipment connected to the shaft or the hole. You can do it. By changing the width and length of the slits (16, 17),
The flexibility of the joint member (12) can be changed. By increasing the width and length of the slit, the flexibility of the joint member can be increased. Therefore, it is possible to appropriately set the flexibility of the joint member (12) according to the structure and specification conditions of the device to be connected, and to effectively prevent breakage and damage of the device.
