舵取装置。 A control valve consisting of a stub shaft rotationally driven by a steering handle, a worm shaft disposed on the same axis as the stub shaft, and a pair of valve members each rotatable with each of these shafts. , a piston that is fitted to the worm shaft via a ball screw and reciprocates within a cylinder provided in the gear housing, and meshes with a rack formed on the piston and rotates as the piston reciprocates. In the integral type power steering device equipped with a sector gear, a reaction force plunger is slidably fitted into a hole formed in the worm shaft, and the reaction force plunger is formed on the outer periphery of the stub shaft. At the same time as being engaged with the engaging part, a discharge hydraulic pressure from the oil pump is applied to the back side of the reaction force plunger, and a ball that can rotate in contact with the housing on the outer circumference of the worm shaft is attached to the back side of the reaction force plunger. An integral type power steering device characterized by the following:
