等角度位置に形成してなる動力舵取装置。A sleeve valve member rotatably fitted to the valve housing is coupled to an output shaft, a rotor valve member rotatably fitted to the sleeve valve member is coupled to an input shaft, and a manual input shaft is applied to the input shaft. In a power steering device that controls supply and discharge of pressure oil to and from a power cylinder by relative rotation between a rotor valve member and a sleeve valve member based on steering torque, the sleeve valve member is configured to control supply and discharge of pressure oil to a power cylinder. It is composed of two members: a sleeve body having a groove and a pair of distribution grooves communicating with the compartment of the power cylinder, and a thin-walled cylindrical body fitted into the sleeve body, and a barrel-shaped body is attached to the outer periphery of the rotor valve member. Port grooves are formed at equiangular positions on the circumference,
In addition, in the thin cylindrical body of the valve member, a cone-shaped port groove is provided between each of the barrel-shaped port grooves and has both edges shaped to replenish both edges of the barrel-shaped port groove. A power steering device formed at equal angular positions on the circumference.
