Abstract

PURPOSE:To improve a vibration protective apparatus in attenuation characteristics as well as increase its load capacity by providing a plurality of spring members located on the periphery of the working member movably provided penetrating through the upper end of a box and between the upper and lower members vertically movably provided in said box. CONSTITUTION:A box 1 on a pedestal 2 is provided with a cylindrical body 3 and a cover 4, in which a vertical through hole 5 is formed. In the box 1, an upper member 6 and a lower member 7 are vertically movably provided. The upper member 6 is provided with a through hole 8 and an upper stopping part 9, and the lower member 7 is provided with a plurality of through holes 14 and a lower stopping part 13. Moreover, a working member 17 is movably provided penetrating through the upper end of the box 1. Also provided are plurality of spring members 24 which are located on the periphery of the working member 17 and between the upper and lower members 6 and 7. When an upward (or downward) shock is applied to the working member 17, the spring members 24 are compressed and the upper (or lower) contact part 20 (or 21) is separated from the upper (or lower) stopping part 9 (or 13).
