A shock absorbing tube comprising a cylindrical main body made of fiber-reinforced plastic and an end member formed internally at an end of the main body, the main body and the end member are capable of separating from each other at an interface therebetween upon the application of a predetermined maximum axial force (Fm) and is capable of moving axially by sequentially enlarging the main body at a predetermined successive axial force (Fs), wherein the main body comprises reinforcing fibers helically wound at an angle of ±5-30° with respect to the axial direction of the main body and the end member is made of a metal or comprises reinforcing fibers hoop wound at an angle of ±70~90° with respect to the axial direction of the end member. The shock absorbing tube is useful for human safety, in particular, for use of propeller shaft and collapsible handle of automobiles.
