Abstract
A vehicle damper of variable damping force including a cylinder, a piston and valves is disclosed. The valves have opening/closing parts and supporting parts. The opening/closing parts and the supporting parts are positioned separately so that a sufficient distance is obtained. Lengthening the distance from the supporting parts to the opening/closing parts makes it possible to reduce the opening and closing force of the opening/closing parts and to obtain highly responsive valves.
