A suspension apparatus with a pair of hydraulic dampers 1 disposed on left and right sides of a vehicle, an upper end side of which is connected to a vehicle body side and a lower end side is connected to an axle side, and a pressure regulating cylinder 2 communicating with piston side oil chambers a of the pair of hydraulic dampers 1. The pressure regulating cylinder 2 has a free piston 26 slidably disposed within a cylinder body 24 and defining a front side chamber h and a back side chamber i within the cylinder body 24. The free piston 26 is slidably encased in a cylinder member and has a partitioning member 27 for defining a closed chamber j and an open chamber k communicating with a front side chamber h on the inner peripheral side of the free piston 26. The partitioning member 27 has a damping valve 4 which communicates between the closed chamber j and the open chamber k, and has a proximal end connected to an extreme end of a rod body 29 elastically supported on the cylinder body 24. The front side chamber h communicates with a piston side oil chamber a of one hydraulic damper 1. The closed chamber j communicates with a piston side oil chamber a of the other hydraulic damper 1 through a through-hole 29b bored in an axial central part of the rod body 29.
