Claims

[Scope of utility model registration request]

A rack and pinion type steering device that steers the front wheels of the vehicle is linked to a rear wheel steering device via a rear wheel steering control device that controls the steering of the rear wheels, and the rear wheels are controlled in response to the steering of the front wheels. In a 74-wheel steering device that also steers a vehicle, a rack gear of the steering device is provided with a rack and pinion type steering force output device in parallel, an end of the rack gear is a first bellows member, and the end of the rack gear is a first bellows member. The end portions are each covered with a second bellows member, the ends of the rack gear and the rack are connected by a connecting rod passing through both the bellows member, and the first and second bellows members are connected to each other through an air passage. A four-wheel steering system for a vehicle, characterized in that the steering force take-off device has a breather that communicates with the second bellows member.
