Abstract: PROBLEM TO BE SOLVED: To improve heat reserving performance, quicken circulation of the blood of subcutaneous tissue of a knee, prevent dryness, and give moisture by forming a supporter main body in a cylindrical shape, and adhering a gas permeability restrainable raw material to a part corresponding to a knee of this supporter main body. SOLUTION: In a supporter 1, a supporter main body is formed in a C-shape and a cylindrical shape, and a circular gas permeability restrainable raw material, to put it concretely, nylon cloth 2 worked by resin is stuck to a part corresponding to a knee of this supporter 1. When this supporter 1 is put, a knee becomes warm, and circulation of the blood is quickened, and sweat oozes out by a sweating action.
