Abstract:
A rear wheel steering device, comprising:a slide shaft supported by a casing so as to be axially slidable;a rotary shaft supported by said casing in parallel with said slide shaft so as to be rotatable around its axial line, and provided with a pair of threaded sections of mutually opposite senses;an electric motor adapted to turn said rotary shaft in either direction;a pair of slide members supported in a rotationally fast manner, and having threaded sections which engage the corresponding threaded sections of said rotary shaft so as to be moveable in mutually opposite axial directions as said rotary shaft is turned in either direction;a pair of clutch units each interposed between a corresponding one of the slide members and the slide shaft for selectively coupling them in an axially fast manner; andat least one actuator for selectively engaging either one of the clutch units.
