Claims

[Scope of utility model registration request]

A power cylinder that generates the steering force for the steering wheel, a sector gear that converts the reciprocating motion of the piston of this power cylinder into rotational motion and transmits it to the sector shaft, and switches and controls the hydraulic pressure to the power cylinder. a control valve; a worm shaft that is threaded through the piston and connected at one end to the sleeve of the control valve; an input shaft rotatably supported on the same axis as the worm shaft and connected to the rotor of the control valve; An integral power steering device including a torsion bar connecting the human shaft and the worm shaft, characterized in that the power steering device is equipped with a centering spring for preloading to counter the relative displacement in the rotational direction of the rotor and the sleeve. .
