Abstract
A bellows type shock absorber comprises a sealed bellows, a shock absorbing column which is provided with a chamber around it inside the bellows and which is along the axial line of the bellows and combined with the bellows so that it physically varies in conjunction with expansion and contraction of the bellows. Also, the bellows type shock absorber may have a through hole which communicates the internal chamber and the outside, and preferably the shock absorbing column is made of a kind of gelled material with a penetration value of approximately 50 to 200. In addition, another shock absorber is provided with the main bellows and a sub-bellows having a spring constant differing from that of the main bellows and a through hole which communicates the internal chamber of the main bellows and the internal chamber of the sub-bellows.
