To improve health by housing a plurality of magnets nearly in the form of a doughnut while stacking them in a cylindrical roller member and freely rotatably supporting the tip of a handle member at one end of the roller member so as to massage shoulders or a back and to further promote the blood circulation at shoulders, the back, etc., by the magnetic action of magnets.

The manual massaging device to be used for mainly recovering stiffened shoulders is provided with the handle member 3 made of stainless steel, etc., nearly in the shape of 7 as a whole and the tip side 3a of this member 3 bent in a direction orthogonal with the member 3 is used as a spindle part 4. Then a roller member 2 obtained by housing the plurality of magnets 7 nearly in the form of a doughnut while stacking them is freely rotatably supported by this part 4. The member 2 is formed into the form of a thin and long cylinder with an steel member and is entirely plated with gold to be processed to avoid generating peeling and discoloration at the time of using. On the other hand, a grasping part 5 consisting of the steel material, plastic, etc., is disposed at the other end 3b of the member 3.
