<p>PURPOSE: To prevent the impartation of unnecessary load on a driving power transmission system by weakly setting the holding force of sliders in a standby position. CONSTITUTION: The circumference of a drum 25 is provided with a pair of loading rails 26, 27 having guide grooves 26a, 27a. The sliders 28, 34 are respectively engaged with these guide groves 26a, 27a. A pair of the sliders 28, 34 and output arms 17, 22 are connected by plural bending and stretching links 29 to 31, 35 to 38. Connecting pins 32, 33, 39 to 41 which connect these bending and stretching links 29 to 31, 35 to 38 are engaged with the guide groves 26a, 27a. A pair of loading rails 26, 27 are formed with long grooves 26e, 27e near the guide groves 26a, 27a existing at the connecting pins 32, 39 in the standby positions of the sliders 28, 34, by which deflection deformation parts 26d, 27d are composed.</p> |
