ABSTRACT:
In a vehicle power steering device, a motor is turned on to rotate in one direction whether a steering wheel is turned clockwise or counterclockwise. A switching mechanism is interposed between a motor armature shaft and an output shaft to change directions of the output shaft rotation relative to the armature shaft rotation in response to turning direction of the steering. The switching mechanism may include electrically controlled coupling/releasing members or mechanically controlled rotation reversing and coupling mechanisms.
