Claim 6:
7. The stabilizer system according to claim 1,
wherein both ends of the stabilizer bar are respectively connected to 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,
wherein the stabilizer device includes:
a pair of cylinders which contain a working fluid and each of which is disposed between the body of the vehicle and a corresponding one of a pair of right and left supported portions of the stabilizer bar such that the stabilizer bar is supported by the body of the vehicle at the supported portions, each of the cylinders being configured to extend and contract in accordance with a rebound motion and a bound motion of a corresponding one of the right and left wheels with respect to the body of the vehicle, each of the cylinders including a first fluid chamber whose volume increases in the rebound motion of the corresponding one of the right and left wheels and decreases in the bound motion of the corresponding one of the right and left wheels and a second fluid chamber whose volume decreases in the rebound motion of the corresponding one of the right and left wheels and increases in the bound motion of the corresponding one of the right and left wheels;
a first communication passage through which the first fluid chamber of one of the cylinders and the second fluid chamber of the other of the cylinders communicate with each other;
a second communication passage through which the second fluid chamber of the one of the cylinders and the first fluid chamber of the other of the cylinders communicate with each other;
an inter-passage communication passage through which the first communication passage and the second communication passage communicate with each other; and
an open/close valve functioning as the switch and disposed in the inter-passage communication passage, the open/close valve being configured to open the inter-passage communication passage when placed in a valve open state and to close the inter-passage communication passage when placed in a valve closed state,

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