<p>A bellows type shock absorber comprising a sealed bellows (10), a shock absorbing column (20) which is provided with an internal chamber around it, inside the bellows coaxially of the bellows aid combined with the bellows so that it physically varies with extension and compression of the bellows, and a through hole (14) which provides communication between the internal chamber and the outside, said shock absorbing column being made of a kind of gelled material with a penetration value of approximately 50 to 200. Alternatively this shock absorber may be provided with a sub-bellows having a spring constant differing from that of the main bellows and a through hole which provides communication between the internal chamber of the main bellows and the internal chamber of the sub-bellows.</p> |
