To provide a vehicular clutch unit capable of suppressing rotation of an output shaft member in a state in which operational force is not applied to an operation lever while maintaining light operational feeling of the operation lever.SOLUTION: A vehicular clutch unit includes: an output side inner ring member; an output side outer ring member; an output side roller; and a roller release member. An operation direction of an operation lever is defined as a forward direction. N+3 (N is natural number) wedge-shaped spaces which become narrow in an opposite direction of the forward direction are defined as a first wedge-shaped space. N+3 wedge-shaped spaces which become narrow toward the forward direction are defined as a second wedge-shaped space. Each of the first wedge-shaped space and the second wedge-shaped space is provided with 1 or more and N or less high friction rollers and at least three low friction rollers. When the operation lever is rotated in the forward direction, the high friction roller is released from a press-contact state between the output side inner ring member and the output side outer ring member by the roller release member earlier than the low friction roller.SELECTED DRAWING: Figure 10

    【課題】軽快な操作レバーの操作感を維持しつつ操作レバーに操作力が作用しない状態での出力軸部材の回転を抑制できる車両用クラッチユニットを提供する。【解決手段】車両用クラッチユニットは、出力側内輪部材と、出力側外輪部材と、出力側コロと、コロ解除部材と、を有する。操作レバーの操作方向を順方向と定義し、順方向と逆向きに幅狭となるN+3個(Nは自然数)の楔状空間を第一楔状空間と定義し、順方向に向かって幅狭となるN+3個の楔状空間を第二楔状空間と定義する。第一楔状空間と第二楔状空間には各々、1個以上N個以下の高摩擦コロと、少なくとも3個の低摩擦コロが設けられている。操作レバーを順方向に回転させるときに、高摩擦コロはコロ解除部材によって、低摩擦コロより先に出力側内輪部材および出力側外輪部材との圧接状態から解除される、クラッチユニット。【選択図】図10
