PURPOSE:To improve the comfortability during drive and the shimmy phenomenon by forming fluid chambers which are varied in capacity according to the forward and rear displacement, at a plurality of front and rear chassis-side axially mounting parts of a A-type suspension arm and communicating these fluid chambers with each other via orifices. CONSTITUTION:In the front and internal end part 32a of an upper arm 32 which is an A-type suspension arm, when rear load, for example, acts on a wheel 71, the cylindrical part 37 of the upper arm 32 is displaced backwards with respect to the support shaft 38 at the chassis side to reduce the capacity of a fluid chamber 46. On the other hand, in the rear and internal end part 32b of the upper arm 32, the cylindrical part 37 is displaced backwards with respect to a support shaft 38 to reduce the capacity of the fluid chamber 53. Then water solution 55 flows to the fluid chamber 53 through the orifice 54 of a long bolt 30. The water solution 55 is subject to the flow resistance in the orifice 54 and this flow resistance is increased or decreased according to the increase or the decrease of load, on account of which the comfortability during drive may be improved and the shimmy phenomenon may be prevented. |
