PURPOSE:To prevent a partition membrane from twist in a strut type suspension system by receiving a cylindrical partition membrane in a hollow rod with both ends being secured fixedly to the hollow rod, to constitute the inside of the membrane into a gas chamber and the outside into an oil chamber. CONSTITUTION:A cylindrical partition membrane 26 made of rubber or the like is received in a hollow rod 17. The outside of the membrane 26 provides an oil chamber 28 and the inside a gas chamber 29. The partition membrane 26 has an opening in an end 31 and is secured fixedly to the upper portion of the hollow rod 17 in the liquid tight condition by a membrane fixing member 33 and nitrogen gas enclosing bolt 34. Also, the bottom end is secured fixedly to a valve seat 41 of a damping force generating mechanism 40 by a fixing member 38. By this constitution flows oil in oil chambers 3, 28 through said generating mechanism 40 to develop the damping force as the hollow rod 17 expands and contracts relative to a cylinder 2, so that the gas chamber 29 acts like a spring. Then, as the upper and lower ends of the partition membrane are fixed, the membrane is never twisted. |
