Claims

[Scope of utility model registration request]

The front, rear, left and right wheels of the vehicle are equipped with springs and hydraulic shock absorbers.The hydraulic shock absorbers divide the cylinder into an upper chamber and a lower chamber using a piston, and an oil passage through an orifice that can freely control the opening and closing of the upper and lower chambers. The damping force variable hydraulic shock absorber is connected to the hydraulic shock absorber, and the extension stroke and pitch are controlled based on the detection signal from the detection means that detects the steering, control, or acceleration state when the vehicle body is traveling with a predetermined rolling or pitching. A hydraulic shock absorber for a vehicle, characterized in that the damping capacity of a set of front, rear, left and right hydraulic shock absorbers is controlled to be higher than the damping capacity of a set of front, rear, left and right hydraulic shock absorbers that are in a contraction stroke.
