Abstract
PURPOSE: To improve the freedom of arrangement positions of a control valve, by forming a cam on circumferential faces of a ring gear in a differential gear mechanism that selectively controls a control valve of a power steering device and selectively actuating the control valve in accordance with a movement of the cam.
CONSTITUTION: When a spool-type control valve 17 of a power steering device is selectively controlled by a differential gear mechanism C that works in accordance with a phase difference generated in an input shaft 3 and screw shaft 6, there is provided a cam 18 in which peripheral faces of a ring gear 14a of said differential gear mechanism C are partially deviated and deformed diametrically. Diametrically in the ring gear 14a, a spool 16 of the control valve 17 is arranged in such a manner as to align its axis. A protruding part prtrusively provided at an end of the spool 16 is contacted to the peripheral face of the ring gear 14a, that is, the cam 18. While at the other end of the spool 16, a compression spring 20 is resiliently installed. Its spring tension allows the spool 16 to be resiliently contacted to the cam 18.
