< Topic >As for buoyancy and gravity as joint making use of with the surfacing power of the tube in the tank of the specified depth which does not reach in the base on the basis of the natural science that, and the gravitation to gravity direction of the weight body relaxation is done it possesses opposite character, offer underwater standing upright joint relaxation and the spinal cord calibrating apparatus which can receive physical remedy such as the lumbar vertebra slipped disk and spinal cord proofreading by re-forming the muscle which is adhered.SolutionsIt can provide the user under the tube and the aforementioned tube which on the water surface it surfaces with the buoyancy of the air, filling up to the person in charge stopping and inside in the upper body side section of the user it is worn by the hip of the bracket and the user where the engagement hole facilities is done to the center, in the upper part the person in charge is stopped in the engagement hole of the aforementioned bracket it is worn by the tube fixed belt and the foot of the user it can provide the clamp, installation and removal can provide weight ones unrestrictedly in the base, making use of the weight which aforementioned weight ones have in the weight body and the aforementioned tube fixed belt which pull the user under the water surface with gravityAs the edge of one side is connected, the other edge being connected by the aforementioned weight body, bullet holding is done the elasticity band which and, has the surfacing power of the aforementioned tube, and the gravity of the aforementioned weight body with the surfacing power of the aforementioned tube and relaxes the joint of the user the gravity of the weight body which is installed in the foot making use of, underwater standing upright joint relaxation and the spinal cord calibrating apparatus which designate that the muscle re-is formed via fixed underwater motion as technical gist.< Selective figure >Figure 1【課題】浮力と重力は反対の性質を
