てなるパワーアシスト機構。 A power cylinder section includes a piston rod that penetrates the inside of the cylinder in a fluid-tight and slidable manner to partition the inside of the cylinder into a pair of left and right oil chambers, and that has both ends connected to left and right tie rods, respectively; An input shaft is housed in a cylindrical portion provided so as to be slidable in the axial direction and slides in the axial direction in response to the operation of the steering handle; a valve spool housed so as to be slidable in the direction; and a valve sleeve that is provided in the cylindrical portion of the piston rod and constitutes a four-way switching valve mechanism that, together with the valve spool, controls the supply and discharge of hydraulic oil to and from the two oil chambers. Equipped with a power assist mechanism.
