Abstract
A rack-and-pinion mechanism (21) for changing a direction of wheels in accordance with a steering input, and a power cylinder (20) providing for power assist for operation of the rack-and-pinion mechanism (21) are provided. A rack shaft (9) of the rack-and-pinion mechanism (21) and a piston rod (3) of the power cylinder (20) are placed parallel to each other. The both ends of the rack shaft (9) and the both ends of the piston rod (3) are respectively linked through connecting members (6, 7). The piston rod (3) and the rack shaft (9) are separated from each other, thereby increasing the design flexibility of them.
