Abstract
There are improved a vibration absorption characteristic and an impact absorption characteristic. In a suspension mechanism 1 of the present invention, first and second dampers (150, 160) are suspended in parallel between an upper frame (120) and a lower frame (110) with mounting angles different from each other. For this reason, the smaller mounting angle the damper has, the smaller a vertical component of damping force becomes, and the damping force which acts on the upper frame (120) and the lower frame (110) which move up and down relatively is moderate in effectiveness as compared with a case of disposing all the dampers at the same mounting angle. Thus, a sense of incongruity in which strong damping force acts abruptly is suppressed and the vibration absorption characteristic and the impact absorption characteristic are improved, which leads to improvement in ride comfort.
