Claims

[Scope of utility model registration request]

A gear case, a piston that fits into the gear case and divides the gear case into two cylinder chambers, an output shaft that has a gear that meshes with a rack provided on the piston, and a ball inserted into a ball screw groove provided on the inner peripheral surface of the piston. The worm shaft is fitted with the worm shaft, the outer sleeve is formed integrally with the worm shaft, the spunyl is fitted into the outer sleeve and cooperates to form a rotary valve, the input shaft is connected to the spool with a pin, and the worm shaft is connected to the worm shaft. A torsion bar that is fitted into a provided shaft hole with a gap and pin-coupled to the worm shaft on the side far from the input shaft to connect the worm shaft and the input shaft, and a valve that supports the outer sleeve and the input shaft and has an oil inlet and an oil outlet. A first oil passage connecting the housing, the outer circumferential surface of the outer sleeve that communicates with the cylinder chamber on the input shaft side, and one oil groove on the inner circumferential surface of the outer sleeve, and the shaft hole of the worm shaft and the inner circumferential surface of the outer sleeve. A second oil groove that connects the other oil groove of the worm shaft, and a seal member provided between the outer circumferential surface of the input shaft and the inner circumferential surface of the worm shaft that fits therein, and a seal member that connects the shaft hole of the worm shaft and the input shaft. A power steering device equipped with an oil chamber that connects the cylinder chamber on the far side.
