<p>PURPOSE:To stabilize actuation with simple constitution without enlarging a mechanism in a spring clutch mechanism. CONSTITUTION:A spring clutch mechanism is provided with a solenoid 35, a rotary lever 37 to rotate to a first position through a plunger 36 when it is turned on and to a second position when it is turned off and a spring clutch 42. The spring clutch 42 is provided with an input side rotary body, an output side rotary body, a coil spring 44 which is wound round these by elastic force and whose one end is engaged with the output side rotary body and an eccentric rotary member 45 to engage with the other end. The eccentric rotary member 45 is provided with an eccentric outer peripheral surface 45c which separates when the rotary lever 37 is put in the first position and pushes against it when the rotary lever is put in the second position, and is provided with an engaging part 45d which takes in and out the plunger 36 by rotating the rotary lever 37 by the eccentric outer peripheral surface 45c according to rotation when the rotary lever 37 is put in the second position and engages with the rotary lever 37 in a position where the plunger 36 is most pushed in.</p> |
