PROBLEM TO BE SOLVED: To provide a clutch device which regulates timing at which a lock member is inserted into an inclined groove, and can alleviate a contact load when a side face of the inclined groove contacts with the lock member.SOLUTION: A driven-side rotating body 5 is made to advance to a drive-side rotating body, and a clutch device is brought into an engaged state. By inserting a pin 69 of the lock member 61 into an inclined groove 57 which is formed at an external peripheral face of the driven-side rotating body 5, and making an inclined side face 57aII of the inclined groove 57 contact with the pin 69, the driven-side rotating body 5 is made to retreat and moved accompanied by the rotation of the rotating body, and clutch-released. A rotating body 92 which rotates synchronously with the driven-side rotating body 5 is arranged, and an eccentric cam 92b which limits the insertion of the pin 69 with respect to the inclined groove 57 according to a rotating position is arranged at the rotating body 92. By this constitution, the insertion of the pin 69 into the inclined groove 57 from only a pin insertion requirement region becomes possible, and it is avoided that the inclined side face 57aII of the inclined groove 57 contacts with the pin 69 in a state that an insertion amount of the pin 69 with respect to the inclined groove 57 is small. |
