ABSTRACT:
A power steering device for a vehicle comprises a steering wheel, a steering linkage operatively connecting the steering wheel to dirigible wheels of the vehicle and a power assisting device inserted into the steering linkage to assist the steering force of the steering wheel. A steering shaft of the steering linkage rotated with the steering wheel to transmit the steering force from the steering wheel to the power assisting device is divided into first and second parts. A pair of coil springs are inserted between the first and second parts of the steering shaft to connect them with each other and is adapted to be elastically deformed to produce a rotational displacement between them when the steering wheel is rotated. A set load is placed on the coil spring so that the coil spring can be elastically deformed only when the steering force from the steering wheel exceeds a predetermined value.
