Abstract:
PURPOSE: To improve the space efficiency and avoid the complicated formation of an operation transmission mechanism.
CONSTITUTION: The damper arrangement structure of a read wheel suspension device for motorcycle which is interposed between a rear arm 21 and a car body fixing part is constituted by providing a buffer spring for softening the shock applied to the rear wheel from a road surface and a damper for suppressing the irregular vertical vibration of the rear wheel.
