Abstract
An object of the present invention is to reduce the size of a shock absorber, and to facilitate adjusting of the damping amount of the shock absorber. The shock absorber 10 has an outer tube 11 and an inner tube 15, wherein a piston rod 14 projects from a base end of the outer tube 11, and a rotative operating part 19 provided in the inner tube 15 projects from a base end of the outer tube 11. An annular piston 27 separates a liquid accommodating chamber 16 into a shock absorbing chamber 28 and an accumulator chamber 29. A flow-rate adjusting hole 48 of the outer tube 11 is composed of a contact surface 51 and an eccentric surface 52. A bypass channel 53 communicating with a communication hole 49 is formed between the eccentric surface 52 and the inner tube 15.
