さくされた液圧式動力舵取装置。 A housing having a stepped inner hole; a piston fluid-tightly and slidably fitted into a large diameter portion of the inner hole of the housing to partition the large diameter portion of the inner hole into a pair of working hydraulic pressure chambers; A worm shaft connected to the piston via a ball screw mechanism, an input shaft connected to the worm shaft via a torsion bar, and liquid-tightly and rotatably fitted into the small diameter inner hole of the housing. an outer valve connected to the worm shaft so as to rotate together with the worm shaft; and an inner valve connected to the input shaft so as to rotate integrally with the worm shaft; a rotary control valve that allows hydraulic fluid to flow into one of the two hydraulic pressure chambers and to flow hydraulic fluid in the other hydraulic pressure chamber into a reservoir, and the connection between the outer valve and the worm shaft is at one end of the outer valve. Hydraulic power is achieved by fitting a pin in a radial direction into a fitting portion between a cylindrical portion formed in the inner hole and projecting into the large diameter portion of the worm shaft and a corresponding end portion of the worm shaft. In the steering device, the pin has a large diameter portion press-fitted into a hole formed at an end of the worm shaft and a small diameter portion fitted into a slit formed in a cylindrical portion of the outer valve. A hydraulic power steering device, wherein the width of the slit is smaller than the outer diameter of the large diameter portion of the pin.
