PURPOSE:To enable a smooth clutching performance by a method wherein a stopper for stopping an engaging section provided at one end of a stationary bevel gear is formed in the shape of L whereby the stopper engages and disengages the engaging section through a clutch wire. CONSTITUTION:The stopper 6 for stopping the engaging section 7 provided at one end of the stationary bevel gear 8 is formed in the shape L so that when the clutch wire 20 connected to a machine frame 1 is pulled back against the force of a spring 21, the stopper 6 is disengaged from the engaging section 7 through a holding member 19 and a rotary shaft 18. As a consequence, in case where the engaging section 7 is released from the stopper 6 through the clutch wire 20 while motive power is interrupted, the stationary bevel gear 8 runs indle by merely engaging a rotary bevel gear 10 and no motive power is transmitted through the gear 8 so that it is possible to perform a smooth clutching action with a slight force. |
