とする４輪操舵装置。 A four-wheel steering device that steers the rear wheels in response to the steering of the front wheels, a front wheel actuating rod that moves in response to the steering of the front wheels, an operating cable that transmits the reciprocating motion of the front wheel actuating rod to the rear wheels, and this operating cable. A rotating plate that rotates due to the reciprocating motion of the rotating plate, a motion converting mechanism that converts the rotation of the rotating plate into a reciprocating motion having a dead zone, a reciprocating shaft fixed to the motion converting mechanism that reciprocates, and a reciprocating shaft of the reciprocating shaft. A spool servo valve that controls the supply and discharge of working fluid from the pump by reciprocating motion, and a rear wheel actuating rod that has a pair of working chambers and reciprocates due to the differential pressure in the working chambers in response to the operation of the spool servo valve. , a neutral spring that holds the rear wheel in a neutral position, and the motion conversion mechanism includes a conversion mechanism that converts rotation of the rotary plate into reciprocating motion, and an intermediate member attached to one end of the conversion mechanism. 4. The intermediate member includes an adjustment pin provided on the intermediate member, and a connecting member that has one end formed with an elongated hole into which the adjustment pin is inserted, and the other end of which the reciprocating shaft is fixed. Wheel steering device.
