Abstract
PURPOSE:To open and close manually when required, without exerting a bad influence on an automatic switchgear, by transferring the driving force to a press-contacting member which is opened and closed freely, through an elastic member which subjects a rotational force to said member in the reverse direction, respectively. CONSTITUTION:Driving force of a reversible motor 6 is transferred to a rotary shaft 4 through a worm gear 8, etc.. Furthermore, this driving force is transferred to an original press-contacting plate 3 through torsion springs 10, 11 for putting the turning force in the reverse direction, respectively levers 13, 16 which are provided with projections 14, 17, respectively, and a pin 19, and the plate 3 is opened and closed automatically. According to this constitution, when the plate 3 which is opened and closed automatically is operated manually if necessary, a plate 2 is opened and closed without exerting influence on the automatic switchgear such as the shaft 4, etc. through the spring 10 or 11.
