To provide a practicable shock absorbing mechanism provided with shock absorbing function using an exchangeable cylindrical material made of aluminum, exhibiting the function relative to unexpected collision situation by one shock absorbing operation, attaining recycling of the whole of the shock absorbing mechanism by exchanging the cylindrical material and useful for energy-saving and reduction of cost not requiring conventional maintenance in the shock absorbing mechanism utilizing inversion by plastic deformation of the cylindrical material made of aluminum or the like.
In the shock absorbing mechanism, a shock absorbing cylindrical material C is arranged between a collision receiver A and an inversion base B and the shock absorbing cylindrical material is press-fitted to a space between them to assemble it. The shock absorbing mechanism is characterized in that the shock absorbing cylindrical material made of aluminum or the like is press-fitted to the space between the collision receiver comprising a circular body in which a spherical surface is formed on one part and a fitting part is integrally provided on the other part and the inversion base in which a cylindrical part is integrally formed on a base.
