Classification: CPC B | IPC B

Claim 7:
8. The stabilizer system according to claim 1,
wherein both ends of the stabilizer bar are connected to one of i) the body of the vehicle and ii) a pair of wheel holding portions that respectively hold right and left wheels and that move upward and downward with the corresponding right and left wheels relative to the body of the vehicle, the stabilizer bar being supported by the other of i) the body of the vehicle and ii) the pair of wheel holding portions,
wherein the stabilizer device includes:
a cylinder disposed between: the one of i) the body of the vehicle and ii) the pair of wheel holding portions; and one of the both ends of the stabilizer bar, the cylinder being configured to extend and contract in accordance with a) a rebound motion of one of the right and left wheels and a bound motion of the other of the right and left wheels and (b) a bound motion of the one of the right and left wheels and a rebound motion of the other of the right and left wheels, the cylinder including a first fluid chamber whose volume increases when the cylinder extends and decreases when the cylinder contracts and a second fluid chamber whose volume decreases when the cylinder extends and increases when the cylinder contracts;
an inter-chamber communication passage through which the first fluid chamber and the second fluid chamber communicate with each other; and
at least one open/close valve functioning as the switch and disposed in the inter-chamber communication passage, each of the at least one open/close valve being configured to open the inter-chamber communication passage when placed in a valve open state and to close the inter-chamber communication passage when placed in a valve closed state;

wherein the controller controls the at least one open/close valve to selectively establish an inter-chamber non-communicating state in which the first fluid chamber and the second fluid chamber do not communicate with each other and an inter-chamber communicating state in which the first fluid chamber and the second fluid chamber communicate with each other, so as to switch the roll suppressing function between the effective state and the ineffective state.
