GAS SPRING TYPE VIBRATION REMOVAL DEVICE

An isolator (2) is provided with a vertical air spring (S1) which vertically supports a mounting base (3), and horizontal air springs (S2, S2, ...) which horizontally support the mounting base (3). The gas springs (S1, S2, S2, ...) respectively have an inner casing (20), an outer casing (200), a piston (30, 300), and a diaphragm (40, 400) which defines an air chamber (23, 230). The air springs (S2, S2, ...) are removably mounted to the outer peripheral surface of the inner casing (20) of the air spring (S1). 隔振器(2)包括沿上下方向支撑承载盘(3)的上下方向空气弹簧(S1)和沿水平方向支撑承载盘(3)的水平方向空气弹簧(S2、S2、...)。上下方向空气弹簧(S1)具有内壳(20)、活塞(30)以及划分出空气室(23)的隔膜(40)，水平方向空气弹簧(S2、S2、...)分别具有：外壳(200)、活塞(300)、以及划分出空气室(230)的隔膜(400)。水平方向空气弹簧(S2、S2、...)安装在上下方向空气弹簧(S1)的内壳(20)的外周面部，且能够拆卸下来。
