To provide a structure capable of preventing a shaft which is connected to a torque transmission shaft, from being vibrated around.SOLUTION: In a shaft 20, a yoke 22 is integrally provided in one end in an axial direction, a slit 30 extending in the axial direction is provided in the other end in the axial direction, and a lock recessed groove 34 extending in a circumferential direction is provided on an outer peripheral surface. In a clamp 21, a lock slit 41 is provided in a portion facing the lock recessed groove 34. The shaft and the clamp are separated from each other and a retaining ring 42 is provided so as to bridge the lock recessed groove 34 and the lock slit 41 in a state where the clamp 21 is externally fitted to the other end of the shaft 20 in the axial direction. In the shaft 20, a pair of shaft-side engage face parts 32 provided at both sides of the slit 30 and a pair of clamp-side engage face parts 39 provided on an inner peripheral surface of an insertion hole 38 of the clamp 21 are engaged in the circumferential direction.SELECTED DRAWING: Figure 2
【課題】トルク伝達軸に接続される軸の振れ回りを抑えることができる構造を実現する。【解決手段】軸方向一端部にヨーク部22が一体に設けられ、軸方向他端部に軸方向に伸長したスリット30が設けられており、外周面に周方向に伸長した係止凹溝34が設けられたシャフト20と、係止凹溝34と対向する部分に係止スリット41が設けられたクランプ21とを、互いに別体とし、シャフト20の軸方向他端部にクランプ21を外嵌した状態で、係止凹溝34と係止スリット41とに架け渡すように止め輪42を設ける。また、シャフト20のうち、スリット30の両側に設けた1対のシャフト側係合面部32と、クランプ21の挿入孔38の内周面に設けた1対のクランプ側係合面部39とを、それぞれ周方向に係合させる。【選択図】図2
