PROBLEM TO BE SOLVED: To provide a shock absorber capable of preventing a hammering sound from occurring.SOLUTION: A shock absorber D serving as means for solving a problem in the present invention, comprises: a cylinder 1; a partition wall member 2 inserted into the cylinder 1 in a slidable manner, for dividing the inside of the cylinder 1 into an extension side chamber R1 and a pressure side chamber R2; attenuation passages 3a and 3b communicating with the extension side chamber R1 and the pressure side chamber R2; a housing 15 forming a pressure chamber R3; a free piston 9 movably inserted into the housing 15, dividing the pressure chamber R3 into an extension side pressure chamber 7 communicating with the extension side chamber R1 through an extension side flow channel 5 and a pressure side pressure chamber 8 communicating with the pressure side chamber R2 through a pressure side flow channel 6; and spring elements 10 and 11 producing urging force for preventing the free piston 9 from being displaced with respect to the housing 15. The shock absorber D includes extension side flow channel regulation means Me for regulating flow passage area of the extension side flow channel 5, and pressure side flow channel regulation means Ms for regulating flow passage area of the pressure side flow channel 6. |
