PURPOSE:To improve rotating stability by inserting coupling members whose one ends are connected to a car body and the others are connected to a member moving up and down with a car shaft and one of whose coupling units is within a limit and length is variable to both ends of a car width direction shaft. CONSTITUTION:In synchronous vertical movement to a car body of right and left wheels, arm tips 4, 4' slide around a line connecting supporting units 2, 2' through coupling members 5, 5'. While, when rolled to one 5' of the coupling members, the member 5' whose length is variable becomes shorter and the other member 5 whose length is variable on the opposite side becomes longer. However as the change of length is limited, roll angle becomes maximum when reached to the limit. This time, push-up force is applied to the arm tip' of the coupling member 5' side and push-down force is applied to the opposite side 4, and twist moment is applied to a shaft 1. By this twist moment action, roll angle can be made constant regardless of up and down movement limit of wheels, and rotating stability can be improved. |
