PROBLEM TO BE SOLVED: To provide a fitness holding jig for inserting a magnetism inclusion aluminum board to a rear face pocket of underwear.SOLUTION: A neodymium magnet 1 (width of 10 MM×thickness of 0.8 MM×length of 25 MM) is included internally with an aluminum board 2 (width of 15 MM×length of 30 MM), then a periphery is closed and processed for forming a magnetism inclusion aluminum board 4 (120 mTesla), the magnetism inclusion aluminum board is inserted into a pocket of underwear, and then it is attached to an upper surface position of a backbone, kidney, and an upper surface position of liver. The magnetism passes through inside of a body, and stimulates iron of hemoglobin in a blood vessel. The aluminum board is free from harmful effect and odor, and toxicity and is hygienic.SELECTED DRAWING: Figure 2COPYRIGHT: (C)2016,JPO&INPIT【課題】磁気封入アルミ盤を下着の裏面ポケットに挿入する健康保持具を提供する。【解決手段】ネオジウム磁石1(巾10MM×厚0.8MM×長さ25MM)をアルミ板2(巾15MM×長さ30MM)で内部封入し、周囲を閉じ加工してなる磁気封入アルミ盤4(120ミリテスラ)とし、下着のポケットに挿入し、背骨、腎臓の上面位置。肝臓の上面位置に取り付ける。磁気が体内を往来し、血管内のヘモグロビンの鉄分を刺激伝導する。アルミ盤は、無害・無臭で毒性がなく衛生的である。【選択図】図2
