PURPOSE:To prevent high vibration of a wheel originated in a road surface from being transmitted to a car body by providing a valve having a delay mechanism to produce a short time lag until resisting action is manifested. CONSTITUTION:A piston 2 is provided with an orifice 7 and an oil path arranged side by side as a passage for oil, and a valve 6 is installed in the oil path. Though the valve 6 is usually adapted to open the oil path by a spring 13, a short time lag is produced to close the oil path because the valve is provided with a delay mechanism comprising an orifice 15 and so on. Accordingly, the oil path is not closed for high vibration of a wheel originated in a road surface to prevent vibration from being transmitted to a car body where resistance is not produced, and the valve 6 closes the oil path for vibration with which the car body vibrates sympathetically at its comparative initial stage to obtain damping action. |
