PROBLEM TO BE SOLVED: To provide a clutch device capable of preventing the releasing connection when abnormality occurs.SOLUTION: In the clutch device for switching transmission/interception of torque between two rotary shafts, a first rotary shaft 36 is configured by forming a plurality of groove parts 42 on an inner periphery or an outer periphery mutually at intervals in a peripheral direction and a second rotary shaft 38 is arranged coaxially with the first rotary shaft so as to be partially overlapped to the first rotary shaft. A plurality of engagement parts 40 are formed on the second rotary shaft so as to be moved in a diameter direction of the second rotary shaft and arrayed mutually at intervals in the peripheral direction of the second rotary shaft. An advance/retreat mechanism advances/retreats the plurality of engagement parts in the diameter direction. Instruction means instructs operation of the advance/retreat mechanism. A plurality of energization means in the advance/retreat mechanism respectively energize the plurality of engagement parts to the plurality of groove part sides in the diameter direction. A solenoid device in the advance/retreat mechanism moves the plurality of engagement parts so as to retreat them from the plurality of groove part sides to predetermined retreat positions against the plurality of energization means. |
