Abstract
A helical structure with a high toughness includes a number of helical elements as an artificial substitute for collagen filament constituting a biological tissue, which can be easily exchanged for a part so as to permanently extend the service life, and which can be easily assembled into a required structure and vice versa. The helical elements are made of wiry materials with a predetermined diameter helically wound with a predetermined lead and pitch so that the diameter of the helix of the helical elements is about two times that of the wiry material. The form of the crest of the structure may correspond with that of the trough, and the trough may be located outside the center of the helix. A number of the helical elements are collectively solidified with their mutual troughs and crests united side by side.
