Abstract
A suspension device includes a shock absorber, an air spring that consists of a compressed gas that is sealed within an air chamber that expands/contracts in volume as the shock absorber extends/compresses so as to constantly bias the shock absorber in an extension direction, and a volume expanding mechanism that expands a volume of the air chamber according to an increase in a compression amount of the shock absorber when the compression amount of the shock absorber has reached or exceeded a predetermined amount.
