Claims

[Scope of utility model registration request]

a valve rotor that rotates integrally with a first shaft rotatably supported within a housing; and a second shaft that rotates integrally with a second shaft coaxially and rotatably connected to the first shaft by a predetermined amount and that rotates integrally with the outer periphery of the valve rotor. a valve sleeve disposed concentrically with the valve rotor, and a switching valve mechanism that is provided between the valve sleeve and the valve rotor and can switch the supply/discharge flow path to each oil chamber of the power cylinder. In the power steering device, the power steering device is equipped with a single-valve type control valve, a port that operates the switching valve mechanism by relative rotation to control the supply and discharge of hydraulic oil to each oil chamber of the power cylinder, and a single valve type control valve. An engaging concave portion or an engaging convex portion having a pair of cam surfaces provided on the other side of the two shafts engages with each of the cam surfaces to restrict rotation, and when one side of the two shafts rotates, the shaft a cam follower that is pushed in a direction, a spring member that elastically presses the cam follower against each of the cam surfaces, and a base end rotatably assembled to the housing and located on the back of the spring member. A power steering device comprising a pushing lever that presses the spring member toward the cam follower during rotation.
