To provide a technique for making amounts of oil flowing into respective damper devices and amounts of oil flowing from respective damper devices uniform, in a state of having one operation part.SOLUTION: A height adjustment device (20) comprises: a cylindrical body (40) whose inside is partitioned into plural oil chambers (Oi) parallel to an axis line (CL1) by a partition wall (42), and which has a cylindrical body oil hole (43) communicated to outside in each oil chamber (Oi); one operation part (50) which is provided rotatably on the cylindrical body (40), which can move along the axis line (CL)1 by being rotated; pistons (60) each of which is stored in each oil chamber (Oi); and plural damper devices (22) which have a damper oil hole (22b) into which oil flowed from a cylindrical body oil hole (43) flows, and which can adjust a height by the amount of oil filled through the damper oil hole (22b).SELECTED DRAWING: Figure 4

    【課題】1つの操作部でありながら、それぞれのダンパ装置へ流入するオイルの量、及び、それぞれのダンパ装置から流出するオイルの量を、より均一にすることができる技術を提供すること。【解決手段】車高調整装置(20)は、隔壁(42)によって内部が軸線(CL1)に並列な複数のオイル室(Oi)に区切られ、オイル室(Oi)のそれぞれに外部に繋がる筒体オイル穴(43)が設けられた筒体(40)と、この筒体(40)に回転可能に設けられると共に、回転させることにより軸線(CL1)に沿って移動可能な1つの操作部(50)と、オイル室(Oi)のそれぞれに収納されたピストン(60)と、筒体オイル穴(43)から流出したオイルが流入するダンパオイル穴(22b)が設けられ、このダンパオイル穴(22b)を介して充填されたオイルの量によって車高を調整可能である複数のダンパ装置(22)と、を有する。【選択図】図4
