Claims

[Claims for Utility Model Registration] (1) When the clutch device is switched from one drive mechanism to another, the lock pawl that self-maintains the state is an engaging body that interlocks the disconnected drive mechanism. When the engagement body is self-retained by being engaged with the engagement body, and in the self-retention state, the disconnected drive mechanism is activated to drive the engagement body, the engagement body is engaged with the engagement body through movement. In a self-retaining clutch device configured to release the locking pawl to return the clutch device to its pre-switching state, the engaging body has a first stage having a locking surface capable of locking the locking pawl. a second step portion which is recessed from the first step portion and is divided into a plurality of sections, and a second step portion having a locking surface capable of locking the lock pawl in the same way as this locking surface;
When the lock pawl locked on the step part slides on the locking surface of the second step part, the first step part and the second step part guide the lock pawl in a direction away from the second step part. A self-holding release mechanism in a self-holding clutch device comprising a lock pawl release guide surface formed at the boundary between two stepped portions. (2) In the self-retaining clutch device according to claim (1) of the utility model registration claim, in which the first stepped portion and the second stepped portion are arranged at equal intervals on the circumference. Self-retention release mechanism. (3) The locking pawl removal guide surface is comprised of an arc surface that divides the boundary between the first step and the second step into an arc shape, as stated in claim (1) or (2) of the utility model registration claim. A self-retention release mechanism in a self-retention clutch device. (4) The lock claw removal guide surface is located between the first step and the second step.
A self-holding release mechanism in a self-holding clutch device as set forth in claim 1 or 2 of the utility model registration claim, which comprises a straight slope with a linearly divided boundary of a stepped portion.
