Claims

[Scope of utility model registration request]

A four-wheel steering device comprising a rear wheel steering angle control means connected to a front wheel steering mechanism via a gear mechanism and controlling a rear wheel steering angle in response to a change in the steering angle of the front wheels during front wheel steering, wherein the gear mechanism rotatably mounted on the steering shaft of the front wheel steering mechanism;
A four-wheel steering device characterized in that the steering shaft and the gear are engaged through an engagement pin that breaks when excessive torque is applied between the steering shaft and the gear.
