Abstract

PURPOSE:To facilitate the adjusting operation of hydraulic cylinders in a full- hydraulic power steering device by carrying out the adjustment of the relative positions of both hydraulic cylinders which are connected in series by means of a steering neutral position correcting means. CONSTITUTION:A steering-form changing changeover valve 18 which changes the operating condition of a rear-wheel hydraulic cylinder 8 with respect to a front-wheel hydraulic cylinder 7 over to different plural types of operating conditions corresponding to different three types of steering forms, is provided on the rear-wheel hydraulic cylinder 8. And, a control device 19 in which a microcomputer is used forms the changeover means 100 thereof. A steering neutral position correcting means 101 which controls the changeover valve 18 so as to make the relative positions of both hydraulic cylinders 7, 8 a proper condition in the indicated steering form according to the control device 19, is built in the control device 19. The correcting means 101 is arranged to operate only in the stopped condition of traveling.
