<p>PROBLEM TO BE SOLVED: To substantially resolve minute positional deviation of a load reception member in a horizontal direction with a simple structure, in a gas spring type vibration isolation device using a piston, such as a dome gimbal piston, into which a rolling mechanism is assembled.SOLUTION: A rolling element 39 is attached to an enlarged-diameter part 31b of the upper end of a support rod 31 constituting a piston 12, and a receiving seat 43 receiving a curve surface 41b of the rolling element 39 in a rollable manner is attached to the lower surface of a load disk 29. The rolling element 39 and the receiving seat 43 are surrounded and constrained by a holding jig 45 in a state where the rolling element 39 and the receiving seat 43 are brought into contact with each other in a vertical direction. The holding jig 45 is indirectly or directly fixed to the load disk 29 and the support rod 31.</p> |
