Abstract
An object of the present invention is to provide a clutch device capable of providing a simple structure, greatly reducing power-application cost and component cost, reducing weight and improving convenience. The clutch device is constituted to include a movable cam plate attached to be rotatable synchronously with a second rotary shaft and to be displaceable in an axial direction, a clutch housing which the movable cam plate is press-contacted with or separated from depending on a displacement of the movable cam plate in the axial direction, and a cam mechanism for separating the movable cam plate from the clutch housing, integrating a first rotary shaft, the movable cam plate and the second rotary shaft with one another and coupling the both rotary shafts to be synchronously rotatable when the first rotary shaft rotates, and for press-contacting the movable cam plate with the clutch housing, integrating the second rotary shaft, the movable plat and the clutch housing with one another and turning the second rotary shaft into an irrotational state when the second rotary shaft rotates.
