PURPOSE:To simplify and facilitate structure and mounting and to improve riding sensation by providing a damping force regulating member capable of regulating the damping force of a damping force generating device and an oil pressure transmitting device to transmit axial displacement of a buffer to the damping force regulating member by means of an oil pressure. CONSTITUTION:When, during running of a vehicle, an up load is exerted on a rear wheel from a road surface, a rear arm 7 is rocked upward against the energizing force of a suspension spring 16, whereby a cylinder 13 of a buffer 12 is contracted. In which case, since a moving amount detecting piston 23 is relatively moved downward within a hydraulic cylinder 20 and a regulating piston 18 is moved upward through the action of working oil 24. Through upward movement of a damping force regulating member 17, a damping force in a damping force generating device is changed. In the damping force, with the increase in an upward moving amount of the rear arm 7, i.e. the stroke of the buffer 12, a moving amount of the regulating piston 18, i.e. the damping force regulating member 17, is increased and a damping force in the damping force generating device is increased. |
