A tandem liquid pressure control device for an anti-lock brake system includes a tandem liquid pressure control cylinder disposed between a tandem master cylinder and the vehicle brakes, and a mechanism for driving the liquid pressure control means for movement in a direction causing a reduction or elevation in braking liquid pressure for an anti-lock operation. The liquid pressure control cylinder contains a first liquid pressure control piston adapted to be driven by the driving mechanism for movement in the direction causing pressure reduction or elevation and a second liquid pressure control piston mounted coaxially with the first piston and movably in a floating way, and defines a first and a second liquid pressure control chambers in which the pressures of the braking liquid are controlled by the movement of the first and second pistons. A solenoid valve is provided for cutting off the supply of the braking liquid from the chambers of the master cylinder to the brakes through the first and second liquid pressure control chambers in response to a cutoff signal inputted from an external source, before the first and second pistons are moved.

An elastic body apparatus includes a pneumatic pressure sealing member formed of a hollow flexible material and sealing therein a high pressure pneumatic gas, a movable member driven by an external force against the pressure of the pneumatic pressure sealing member, a fixed shell enveloping a fixed portion of the pneumatic pressure sealing member, and an elastic shell having plate spring portions for applying a spring force in the same direction as the pressing direction of the pneumatic pressure sealing member to the movable member, and disposed at a position enveloping a displacing portion of the pneumatic pressure sealing member. The elastic shell serves as a shell and a spring body, and even if the pressure of the pneumatic pressure sealing member is increased, the pneumatic pressure sealing member is prevented from being deformed in excess of a normal level, and the pressure is transmitted to the movable member through the pneumatic pressure sealing member.
