Power steering apparatus
 A power steering apparatus for an automobile or other vehicle has a motor which rotates a steering shaft through an electromagnetic clutch and a worm gear reduction gear. When the clutch is engaged, the rotation of the motor causes the rotation of the steering shaft. When the clutch is disengaged, the steering shaft is not connected to either the reduction gear or the motor and can therefore be rotated manually with the same force as for a manual steering apparatus. The reduction gear and the electromagnetic clutch are coaxially disposed around the steering shaft.
