Claims

[Scope of utility model registration request]

A dividing part is formed in any part of the stabilizer device including a connecting part of the left and right suspension members that have a relationship with each other, and a cylinder is provided at the divided end on one side. Further, a piston is provided at the other divided end to separate the inside of the cylinder into two hydraulic pressure chambers, and further, at a portion of the cylinder wall located near the outer end of each of the two hydraulic pressure chambers, First and second through holes are bored, and a third through hole is formed approximately in the center of both through holes.
A first opening/closing valve is provided in a first communicating passage in which a through hole is bored and connects the first and second communicating holes, and a second opening and closing valve is provided in a second communicating passage arranged in parallel to the first communicating passage. In the torsion bar type stabilizer device, the cylinder wall is provided with a check valve that connects a flow passage communicating with the third passage hole and allows the working fluid to flow from the third passage hole only in the direction of the first and second passage holes. a plurality of pairs of through holes are bored between the first and second through holes at substantially symmetrical positions with respect to the third through hole;
A torsion bar type stabilizer device characterized in that an on-off valve is provided in each of the communicating passages that communicate the pair of through holes.
