CLUTCH DEVICE AND MOTOR UNIT

WIPO Patent Application WO/2021/100793

A1

[Problem] To provide a clutch device and a motor unit which make it possible to exhibit clutch torque in a stable manner. [Solution] An input disk (11) and an output disk (12) in a clutch device (10) are provided so as to be connectable/separable in an axial direction A and have, on mutually opposing surfaces (11b), (12b), tooth parts (11a), (12a) that can be fitted thereto/separated therefrom in association with connection/separation. The tooth parts (11a), (12a) have recess parts (11c), (12c) and projection parts (11d), (12d) that extend in a radial direction R so as to be provided alternately in a circumferential direction θ. The recess parts (11c), (12c) and the projection parts (11d), (12d) are formed in a curved surface state where a circumferential width W is continuously extended toward the outer side of the radial direction R. In a state where the tooth parts (11a), (12a) of the input disk (11) and the output disk (12) are fitted to each other by being pressed by a biasing member (13), an engagement force for engaging in the axial direction A is set to be greater on the inner side of the tooth parts (11a), (12a) in the radial direction R than the outer side thereof.
