ABSTRACT:
A cylindrical sleeve and a reaction force receiver are fixed on a ceiling plate so as to form a passage along which a rod-like member is placeable and bent by a bending pin rotating about an output shaft driven by an electric motor through a speed-reduction gear train. A wall is formed in parallel with a front end surface of the reaction force receiver in an opposed relationship with each other. A plurality of surfaces, formed on the front end of the reaction force receiver, are inclined with each other. The rod-like member is supported along one of the plurality of surfaces.
