WIPO Patent Application WO/2018/055690
Kind Code:
A1
Abstract:
[Purpose] To provide a stretching tool that has a sufficient stretching effect on deep fascia while also ensuring that a load imposed on skin, muscles, or joints will not be excessive. [Solution] This stretching tool is provided with: two spheres of identical size, each with a two-layer structure consisting of an inner shell and an elastic outer covering layer which is affixed to the surface of the inner shell and which has a hardness relatively less than that of the inner shell; and a connecting section that connects the inner shells of the two spheres so that an extended axial center line passes through the centers thereof, and that is formed from a material that is the same as or different from that of the inner shells. On the outer surfaces of the two spheres, formed are a plurality of ridges that have saw-blade-shaped cross-sections in which mountains and valleys are repeated in the circumferential direction and that extend over the extended axial center line continuously from an end section on the outermost side of each of the two spheres toward the connecting section.
