Abstract
PURPOSE:To simplify the structure by making the operating direction of an output shaft and the operating direction of a connection spring and a cutoff spring equal and vertical to the rear plate of an operating unit box and fixing the fixed side ends of the connection spring and cutoff spring from the vertical direction to the rear side respectively. CONSTITUTION:A cutoff spring 9 is arranged in an operating unit box 4 on a shaft near an output shaft 20, a connection spring 10 is arranged so as to apply the spring force vertically to a rear plate 6 and stored in a spring case 28 outside the operating unit box 4. The operating direction of both springs 9, 10 and the operating direction of the output shaft 20 are made equal, and fixed end sides of both springs 9, 10 are fixed so that the spring force is applied vertically to the rear plate 6. No angular moment is applied to the rear plate 6 unlike in the past. If the rear plate 6 is manufactured with the thickness to withstand the spring force and reaction force or the like of both springs 9, 10, the other portion 7 forming the operating unit box 4 can be decreased in thickness, and a bracket 8 supporting the rotary shaft of each lever is simplified.
