  • Publication number: 20100320655
    Abstract: A shock absorber that absorbs a vibration using a working fluid charged into a first chamber and a second chamber comprises a tube body, an inserted body, a tip end of which is inserted into the tube body from an end portion of the tube body, and a partition wall portion that is provided on the tip end of the inserted body to be capable of sliding within the tube body and partitions an interior of the tube body into the first chamber and the second chamber. The shock absorber comprises a connecting portion that is provided within a partition wall portion sliding region of the tube body and connects the first chamber and the second chamber when the partition wall portion passes thereby.

  • Patent number: 7744097
    Abstract: A hydraulic cushion unit (1) is interposed between a frame and a rear wheel axle of a bicycle. A surplus hydraulic oil discharging passage (31a) discharges surplus hydraulic oil from the hydraulic cushion unit (1) to an accumulator (2) in contraction. A damping force generating valve (3) which maintains a closed state below a predetermined cracking pressure is disposed in the surplus hydraulic oil discharging passage (31a). A bypass passage (4) which bypasses the damping force generating valve (3) and a bypass valve (4) which opens and closes the bypass passage (L) are further provided. By closing the bypass valve (4) when pedaling of the bicycle is performed to start the bicycle, squatting of the bicycle is prevented while maintaining a shock absorbing function of the damping force generating valve (3).
