<p>PROBLEM TO BE SOLVED: To widen a control range of the hardness of a treatment tool, and to improve the responsitlvity. SOLUTION: This machine is provided with a treatment tool 1, with which a magnetic viscous fluid 3 is sealed in a flexible outer cover 10, a magnetic field generating means 12 for varying the quantity of magnetism to be applied to the magnetic viscous fluid 3 in the treatment piece 1 and a driving means for making the treatment piece 1 perform massage operation. The hardness of the treatment tool is controlled by utilizing the viscosity change of a magnetic viscous fluid having a remarkable viscosity change to the strength of the magnetic field in magnetic fluids.</p> |
