<p>PURPOSE:To obtain a power steering apparatus which can use the revolution force of a motor directly as steering force which has high reliability and a simple structure, by transmitting the revolution of the motor by a torque sensor in which the position of a movable body is changed according to the input torque of a steering shaft and transferring the movable body in the direction for off- setting the change of position of the movable body. CONSTITUTION:When a steering wheel is revolved rightward, a movable body 10q fitted onto the shaft of a gear 10o is transferred integrally with the gear 10o. A torque sensor 11 generates the electric signal corresponding to the amount of shift of a sensor part 11a, and said signal is supplied into a controller, and a motor 10f is revolved in correspondence with the supplied signal. If the motor 10f is set to revolve rightward in this time, said revolution is transmitted to a gear 10j through a gear 10i, and a steering shaft 10b is revolved rightward. Therefore, the steering shaft 10b is revolved in the same direction to the steering shaft 10a, and a steering apparatus is controlled, and rightward turning is performed.</p> |
