(See Fig. 6(c).)
- the lower end of the driven projection 81 slides (or slides) along the first descending inclined surface 311, and this sliding is caused by the driven projection 81 coming into contact with the first turning limiting surface 312 for further clutching operation.

The position of the clutch 90 at this time is the disconnected position. (See FIG. 6(e).) Since the clutch 90 is supported by the first descending inclined surface 311 while the clutch 90 is in the disconnected position, the control unit 17 controls the solenoid 50. The current applied to the coil is cut off to reduce power consumption.
