Abstract
A clutch device includes a sector gear, a cam, an electromagnetic solenoid, a first lever, a second lever, a first spring, and a second spring. The cam includes a slide portion. The first lever engages with the electromagnetic solenoid and includes a first restricting portion. The second lever includes a hook and a second restricting portion. The first spring is configured to urge the second lever in a direction in which the first restricting portion and the second restricting portion contact each other. The second spring is configured to, when the electromagnetic solenoid is in a de-energized state, move the first lever. The slide portion of the cam has a surface configured to, when the electromagnetic solenoid is in an energized state, press the hook in a direction opposite to an urging direction of the first spring such that the second restricting portion is separated from the first restricting portion.
