PROBLEM TO BE SOLVED: To provide a shock absorber capable of making both compatible in security of the stroke length and a mounting characteristic to a vehicle.SOLUTION: A problem solving means is the shock absorber D including a cylinder 1, a piston 2 slidably inserted into the cylinder 1 and partitioning the inside of the cylinder 1 into an extension side chamber R1 and a pressing side chamber R2, damping passages 3a and 3b for communicating the extension side chamber R1 and the pressing side chamber R2, a pressure chamber R3, a free piston 9 movably inserted into the pressure chamber R3 and partitioning the pressure chamber R3 into an extension side pressure chamber 7 communicated with the extension side chamber R1 via an extension side flow passage 5 and a pressing side pressure chamber 8 communicated with the pressing side chamber R2 via a pressing side flow passage 6, and a spring element 10 for generating energizing force for restraining displacement of the free piston 9 to the pressure chamber R3. The pressure chamber R3 is formed in a cylindrical shape of covering the outer periphery of the cylinder 1. |
