Abstract: A shock absorbing device includes an upper cap, a plurality of absorbing blocks, a plurality of middle elements and a lower cap, each of the upper cap, the lower cap and the middle elements has a hole centrally defined therein for a shaft extending therethrough, the absorbing block disposed between the upper cap and the following middle element, every two adjacent middle elements and the middle element adjacent the lower cap and the lower cap, the upper cap, the lower cap and each of the middle elements having a skirt portion extending vertically from a respective periphery thereof, the adjacent skirt portions will abut each other because of the deformation of the absorbing block disposed therebetween wherein the deformation does not yet reach an elastic fatigue point of the absorbing block.
