Claims

[Scope of utility model registration request]

(1) It has a means for measuring the distance between the road surface and a predetermined part of the vehicle body, and is characterized in that the steering force can be controlled in accordance with a signal from a rough road detector that detects a rough road based on a change in the distance. power steering.

(2) The power steering according to claim 1, which is a registered utility model, characterized in that the steering force is increased when the rough road is detected.
