Abstract: There is provided a health instrument with which, even though a treating person is a treatment subject, the treating person is capable of performing a predetermined treatment, and which efficiently restores a human soft tissue into a normal state by properly coping with a difference in human soft tissue such as a fascia or a muscle, which is induced by a difference in physique, or the like. There is provided a health instrument with a rod shape which has at least one or more grip portions and a treatment portion extending along a length direction, in which the treatment portion has a curved portion in a width direction, and in a cross-sectional shape which is obtained when cutting the treatment portion at a midpoint along the length direction, has four or more protrusions on a periphery of a cross section, and tip portions of the protrusions are curved.

Abstract: A stretching tool includes: 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. The spheres' exterior surfaces have ridges that have saw-blade-shaped cross-sections and 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.

Abstract: Provided is a stretching slider excellent in compactness and lightweightness and exhibiting high stability and slipperiness. A stretching slider includes a plate-shaped member having a first surface as a front surface and a second surface as a back surface and a plurality of ball rollers provided on the second surface for moving the plate-shaped member in all directions along a horizontal direction.
