Abstract
Provided is a clutch unit in which an output-side outer ring member is attached to a base plate without welding. A clutch unit (100) includes an output-side clutch (60) and a housing (11) that accommodates the output-side clutch (60). The output-side clutch (60) includes an output-side outer ring member (62). The output-side outer ring member (62) and the housing (11) have an engagement protrusion (62s) and an engagement groove (11s) that engage with each other to restrict relative rotation therebetween.
Claims8
A clutch unit for use in a vehicle seat, the clutch unit comprising:
- an operation lever that is rotatable about a rotation axis;
- an output shaft member that is rotatable about the rotation axis and outputs, to the vehicle seat, an operation force applied to the operation lever;
- an input-side clutch that is driven by the operation lever and transmits rotation of the operation lever to the output shaft member;
- an output-side clutch that transmits a rotational torque of the input-side clutch to the output shaft member and limits transmission of a rotational torque from the output shaft member to the input-side clutch;
- and
- a housing that accommodates at least the output-side clutch
- wherein the output-side clutch includes:
- an output-side inner ring member that rotates integrally with the output shaft member about the rotation axis;
- an output-side outer ring member that is attached to the housing;
- and
- an output-side intermediate transmission member that is rotatably provided between the output-side inner ring member and the output-side outer ring member, and transmits a rotational torque of the output-side inner ring member to the output-side outer ring member, and
- wherein the output-side outer ring member and the housing have engagement structures that engage with each other to restrict relative rotation therebetween.
