Clutch unit
A clutch unit includes a lever-side clutch section configured to control transmission and interruption of rotational torque input by a rotation of an operation lever, and a brake-side clutch section configured to transmit the rotational torque from the lever-side clutch section to an output side and interrupt rotational torque that is reversely input from the output side. The lever-side clutch section includes a side plate to which the operation lever is fixed and an outer ring member that fits with the side plate. The brake-side clutch section includes a cover whose rotation is restricted. An angle regulating part configured to regulate a rotation angle of the operation lever is disposed radially inside of outer peripheral edges of the outer ring member and the cover and includes a claw of the outer ring member and a through hole of the cover.
1. A clutch unit comprising:
an input-side clutch section configured to control transmission and interruption of rotational torque input by a rotation of an operation lever; and
an output-side clutch section configured to transmit the rotational torque from the input-side clutch section to an output side and interrupt rotational torque that is reversely input from the output side, wherein
the input-side clutch section includes a side plate to which the operation lever is fixed and an outer ring member that fits with and is fixed to the side plate,
the output-side clutch section includes a stationary member whose rotation is restricted, and
an angle regulating part configured to regulate a rotation angle of the operation lever is disposed radially inside of outer peripheral edges of the outer ring member and the stationary member.
2. The clutch unit according to claim 1 , wherein the angle regulating part includes a claw provided on the outer ring member and a locked part provided on the stationary member, the locked part accommodating the claw so as to be movable in a circumferential direction, and locking the claw at a moving end of the claw.
3. The clutch unit according to claim 1 , wherein the input-side clutch section and the output-side clutch section are incorporated in an automobile seat lifter.
4. The clutch unit according to claim 2 , wherein the input-side clutch section and the output-side clutch section are incorporated in an automobile seat lifter.
