摘要： PROBLEM TO BE SOLVED: To provide a damper in which size of amplitude of vibration and/or impact that can be coped with is unchanged to achieve higher damping efficiency, in which damping performance capable of coping with vibration and/or impact added in a desired direction in two or three dimensions can be achieved, and in which compactness and economy are achieved.
SOLUTION: In this device, a plurality of oil dampers are provided in parallel, piston rods for part of oil dampers are set in opposite directions to directions of the other piston rods, and cylinders are integrated. An intermediate plate 46 is provided between installation bases 2 and 3. Oil damper devices 1a and 1b in Z-axis directions are installed between the installation base 2 and the intermediate plate 46. For oil damper devices 7a and 7b in X-axis directions and an oil damper device 7c in a Y-axis direction, their piston rods are installed on the intermediate plate 46 and the installation base 3 through mechanisms 41a-41c and 42a-42c which slide perpendicularly to respective action axes.
