Abstract
An improvement to an electrically driven power steering apparatus which utilizes an electric motor is disclosed. A bevel gear of a greater diameter is mounted on a steering shaft so as to be axially displaceable thereon, and an urging mechanism is connected between the bevel gear and the steering shaft. The urging mechanism renders the bevel gear to be incapable of rotation relative to the steering shaft, and also urges the teeth thereof toward the teeth of a bevel gear of a reduced diameter which is coupled to the electric motor. This prevents a backlash from occurring between the both bevel gears, thus preventing the occurrence of sounds of percussion as the both gears abut against each other.
