Japanese Patent JP3244739
Kind Code:
B
Abstract:
PURPOSE: To improve the space efficiency and sufficiently secure the rigidity of a rear arm.
CONSTITUTION: The damper arrangement structure for a rear wheel suspension device 29 for motorcycle is equipped with a buffer spring for softening the shock applied to a rear wheel from a road surface and a damper for suppressing the irregular vertical vibration of the rear wheel and is interposed between a rear arm and a car body fixing part. In this case, the buffer spring is formed from a strip plate shaped leaf spring 31 and arranged under the engine.
