PROBLEM TO BE SOLVED: To provide a clutch device in which limitation on resolution depending on a rotor outer diameter is suppressed, and which has an encoder capable of detecting rotation of a rotor connected to an operation object even when a clutch is disengaged.SOLUTION: A clutch device is configured by including: a rotation body for rotating by a driving source; an output shaft for outputting a torque with respect to an operation object; a rotor having a tooth row on a side surface and for integrally rotating with the output shaft; a clutch plate provided in a manner movable between a connection position in which it is connected to both the rotation body and the rotor, and a release position in which at least one connection out of with the rotation body and with the rotor is released; an electromagnetic coil for moving the clutch plate between the connection position and the release position by an electromagnetic force; an encode board having a part to be detected and for rotating by transmission of the force via the tooth row; and an encode sensor for detecting the part to be detected.SELECTED DRAWING: Figure 3 |
