[Object] To provide a clutch apparatus that can smoothly switch from a clutch engaged state to a clutch non-engaged state, while tooth jump does not occur even with a small-sized clutch apparatus.[Solving Means] A recessed portion 153 is provided in a cam face of a cam 45. A cam shaft 13 is configured to pivot by a predetermined amount as a cam follower 51 is fitted in the recessed portion, and, when the cam initiates to engage the cam follower, it enters a clutch engaged state. A driven side gear 99 is pivoted by a predetermined amount as the cam follower is fitted in the recessed portion and, thereby, a clutch member 93 is rotated by a predetermined amount in a direction in which a toothed portion 94 is spaced apart from a drive side gear 92. In a state where the cam follower is not fitted in the recessed portion, when the clutch member 93 switches its clutch state, at least a portion of a swing locus of the toothed portion 94 of the clutch member 93 maintains a clearance with a gear tooth of the drive side gear 92.
