A torsional rigidity control device capable of controlling a moment provided to stabilizers ( 1 f) and ( 1 r) against the moment based on an external moment loaded from the outside to the stabilizers ( 1 f) and ( 1 r), comprising a moment variable mechanism for varying the moment loaded on the stabilizers ( 1 f) and ( 1 r) by regulating a fluid pressure supplied from a fluid pressure source driving rotary actuators ( 2 f) and ( 2 r) connected to the intermediate parts or one ends of the stabilizers ( 1 f) and ( 1 r) or the cylinders ( 51 f) and ( 51 r) connected to one ends of the stabilizers ( 1 f) and ( 1 r), characterized in that the necessary value of the fluid pressure for driving the rotary actuators ( 2 f) and ( 2 r) or the cylinders ( 51 f) and ( 51 r) is calculated based on the value of the external moment, the value of the fluid pressure supplied to the rotary actuators ( 2 f) and ( 2 r) or cylinders ( 51 f) and ( 51 r) is compared with the necessary value of the fluid pressure, and based on the compared result, the fluid pressure is regulated to control the moment, whereby a stable torsional rigidity can be developed by stabilizing a fluid pressure in a pressure chamber to increase a riding comfortableness at the time of rolling of a vehicle even when the device is mounted on the vehicle.
