Summary:To improve practicability of a stabilizer system.SOLUTION: A stabilizer system is equipped with stabilizer devices 12' and 14' that has (a) stabilizer bars 16 and 60, (b) hydraulic cylinders 26 and 72 being interposed between the stabilizer bars and a vehicle body 24 or a wheel holding member 18, and dividing two liquid chambers 26c and 72c changing capacities with vertical movement of the wheel holding member, and (c) switch mechanisms 42' and 80' that switch prohibition and permission of inflow/outflow of working fluid to the two liquid chambers, thereby switching validation/invalidation of a roll suppression effect of the vehicle body by the stabilizer bars. Low pressure chamber fluid pressure lowering preventive means 94, 96 are provided, which prevent the lowering of a pressure of the liquid chamber with the lower pressure of the working fluid of the two liquid chambers, in a state where the roll suppression effect is validated. A cavitation phenomenon is the cylinders can be prevented.SELECTED DRAWING: Figure 7 【課題】 スタビライザシステムの実用性を向上させる。【解決手段】 (a) スタビライザバー16,60と、(b) そのスタビライザバーと車体24若しくは車輪保持部材18との間に介装され、内部に、車輪保持部材の上下動に伴って容積が変動する2つの液室26c,72cが区画された液圧式シリンダ26,72と、(c) それら2つの液室に対する作動液の流出入の禁止と許容とを切り換えることで、スタビライザバーによる車体のロール抑制効果の有効化と無効化とを切り換える切換機構42',80'とを有するスタビライザ装置12',14'を備えたスタビライザシステムにおいて、ロール抑制効果が有効化されている状態における、2つの液室のうちの作動液の圧力が低い方の、その圧力の低下を防止する低圧室液圧低下防止手段94,96を設ける。シリンダにおけるキャビテーション現象が防止できる。【選択図】 図7
