装置。 A cylindrical input shaft that rotates when a handle is operated, a ball screw provided coaxially with this input shaft, one end fixed to the inner periphery of the ball screw, and the other end fixed to the inner periphery of the input shaft. a torsion bar that elastically connects the ball screw to the ball screw; a ball nut piston that is screwed to the ball screw via a ball and moves in the axial direction; and a cross shaft that has a sector gear that meshes with rack teeth formed on the ball nut piston. , a side cover that surrounds this cross shaft, a gear housing that surrounds the ball nut piston and also serves as a power cylinder that communicates with the inside of the side cover and forms oil chambers on the left and right sides of the ball nut piston, and a gear housing that is fixed to the gear housing. a servo valve that is provided in the valve housing and controls the supply and discharge of pressure oil to and from the oil chambers of the power cylinders through oil flow paths; In the power steering device, an oil flow path that communicates between the servo valve and the oil chamber of the cylinder on the servo valve side is connected to a first oil passage that communicates between the servo valve and an inner upper part of the side cover. A second fluid passage communicating with the inner upper part of the side cover and the upper end of the cylinder oil chamber on the servo valve side.
A power steering device comprising an oil flow path.
