PROBLEM TO BE SOLVED: To improve a suspension at low cost by simplifying the structure of stroke lock means.SOLUTION: A suspension includes a suspension body F and stroke lock means R of stopping the suspension body F from expanding and contracting, and the stroke means R includes a cylindrical member 1 coupled to a vehicle body side and having one chamber A and the other chamber B formed inside side by side in an axial direction, a partition wall body 2 fixed in the cylindrical member 1 and partitioning off the one chamber A and the other chamber B, flow passages L1, L2 linking the one chamber A and the other chamber B to each other, a valve 3 blocking communication between the flow passages L1, L2 in a stroke lock mode, and a shaft member 4 coupled to a wheel side and inserted into the one chamber A in a retractable state. The one chamber A is filled with hydraulic fluid, and hydraulic fluid is reserved in the other chamber B to form a liquid reservoir chamber b1. |
