ABSTRACT:
A power steering device for steering an outboard engine on a small boat has a hydraulic cylinder unit for angularly moving a steering arm of the outboard engine, the hydraulic cylinder unit having a piston rod connected to the steering arm, and a directional control spool valve for supplying a hydraulic pressure to the hydraulic cylinder unit to move the piston rod. A control cable controls the directional control spool valve in response to operation of a steering wheel. The control cable has a core having an end coupled to the piston rod and a sheath covering the core and having an end coupled to the spool of the directional control spool valve. The hydraulic cylinder unit has a cylinder divided by a piston into a first oil chamber through which the piston rod extends and a second oil chamber remote from the piston rod. The directional control spool valve has an oil passage which interconnects the first and second oil chambers when the directional control valve supplies the hydraulic pressure to the second oil chamber.
