Patent ID: 10683898

Abstract:
A clutch device includes a drive transmitting shaft; a driving-side engaging member; and a driven-side engaging member. A driving force is transmitted from the driving-side engaging member to the driven-side engaging member. The driving-side engaging member has a driving-side clutch tooth, and the driven-side engaging member has a driven-side clutch tooth capable of being engaged with and released from the driving-side clutch tooth. The driving-side clutch tooth and the driven-side clutch tooth have drive transmitting surfaces inclined so as to axially attracting each other in engagement with each other. At least one of the driving-side clutch tooth and the driven-side clutch tooth has a functional surface on a free end side relative to the drive transmitting surface with respect to the engaging direction. The functional surface is inclined so as to axially separating from a surface of the other clutch tooth in engagement therewith.
