Abstract
A clutch device includes; i) a clutch mechanism including a friction engagement member capable of rotating relative to a rotating member and a clutch member that is supplied with restoration force in a direction in which the clutch member departs from the friction engagement member by a restoration spring; and ii) a cam mechanism including; a cam member that is arranged in parallel to the clutch mechanism along a rotation axis line of the rotating member and that is incapable of rotating relative to the rotating member; and a cam follower capable of rolling on a cam surface that exists between the cam member and the clutch member. The cam angle is set to make torque applied to the clutch member due to reaction force accompanied by friction engagement with the friction engagement member larger than torque applied to the clutch member by thrust force caused by an activation of the cam mechanism.
