Claims

[Scope of utility model registration request]

A rotatably provided knuckle, a rear wheel attached to the knuckle, a steering actuator that rotatably drives the knuckle to steer the rear wheel, and a steering actuator that rotates the knuckle to steer the rear wheel. A control valve mechanism that controls hydraulic pressure supplied to a steering actuator,
The above-mentioned steering actuator includes a housing and a rotor rotatably provided within the housing, and a vane boss portion is formed at one axial end of the rotor, and a lock portion is formed at the other axial end of the rotor. A vane is provided protrudingly on the vane boss portion, and is formed in a lock recess in the lock portion, and is fitted in the lock recess on the housing side to lock the rotor in a neutral position. A rear wheel steering device characterized by having a lock pin.
