PROBLEM TO BE SOLVED: To provide a clutch capable of suppressing degradation of locking performance due to abrasion.SOLUTION: A clutch 40 includes an annular collar 41, a driving-side rotor 42 rotated and driven, a driven-side rotor 45 disposed coaxially with the collar 41 at an inner side of the collar 41, and rolling elements 44 disposed between the collar 41 and the driven-side rotor 45. The clutch 40 transmits forward/backward rotational drive of the driving-side rotor 42 to the driven-side rotor 45 in the rotational drive state of the driving-side rotor 42. The clutch 40 blocks the rotation in a first direction R1 of the driven-side rotor 45 by holding the rolling elements 44 between the driven-side rotor 45 and the collar 41, and permits the rotation of the driven-side rotor 45 in a second direction R2 opposed to the first direction R1, in a non-rotational drive state of the driving-side rotor 42.SELECTED DRAWING: Figure 8

    【課題】摩耗によるロック性能の低下を抑制できるクラッチを提供する。【解決手段】クラッチ40は、環状のカラー41と、回転駆動される駆動側回転体42と、カラー41の内側において該カラー41と同軸上に配置された従動側回転体45と、カラー41と従動側回転体45との間に配置された転動体44とを備える。クラッチ40は、駆動側回転体42の回転駆動状態では、該駆動側回転体42の正逆回転駆動を従動側回転体45に伝達する。そして、クラッチ40は、駆動側回転体42の非回転駆動状態では、従動側回転体45とカラー41との間に転動体44が挟持されることで従動側回転体45の第1の方向R1への回転を阻止する一方、該第1の方向R1とは反対の第2の方向R2への従動側回転体45の回転は許容する。【選択図】図8
