Abstract
A hydraulic cushion unit () is interposed between a frame and a rear wheel axle of a bicycle. A surplus hydraulic oil discharging passage () discharges surplus hydraulic oil from the hydraulic cushion unit () to an accumulator () in contraction. A damping force generating valve () which maintains a closed state below a predetermined cracking pressure is disposed in the surplus hydraulic oil discharging passage (). A bypass passage () which bypasses the damping force generating valve () and a bypass valve () which opens and closes the bypass passage (L) are further provided. By closing the bypass valve () 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 ().
