PROBLEM TO BE SOLVED: To easily optimize the ratio of a spring constant to a vertical load of an elastic body to a spring constant to a horizontal load without making a device complicate and large-sized. SOLUTION: An intermediate plate 28 is buried in the intermediate part in the axial direction of an elastic body 18, partitions the elastic body 18 into an upper elastic piece 30 and a lower elastic piece 32, and is fixed to the elastic pieces 30, 32. The upper elastic piece 30 is connected and fixed to a fixing plate 16, the lower elastic piece 32 is connected and fixed to a supporting cylinder 20. The elastic body 18 can be functioned as two elastic bodies comprising the upper elastic piece 30 and the lower elastic piece 32 arranged in series to tube vertical stress in the axial direction, and the elastic pieces 30, 32 can be functioned as an approximate single elastic body to the shearing stress in the direction perpendicularly crossing to the axial direction. |
