<p>PROBLEM TO BE SOLVED: To provide a magnetic force device for realizing a superior motion keeping function.SOLUTION: A magnetic force device 100 comprises a fixed magnet part 20 fixed to a disk-like fixing member 10 as prescribed fixing means and a movable magnet part 50 arranged so as to be movable within a magnetic force influencing region of the fixed magnet part 20 in a prescribed direction (a direction of an arrow line R1 along a virtual circle R). The fixed member 10 is formed by non-magnetic material. The fixed magnet part 20 comprises two column-like magnets 20x, 20y arranged to make a V-shape under an attitude in which the magnetic poles may show inverse phases to each other, cover materials 21x, 21y made of magnetic material enclosing the outer circumferences of the column-like magnets 20x, 20y and a connecting member 23 made of magnetic material for connecting magnetic poles 22x, 22y together positioned at base ends where the two column-like magnets 20x, 20y approach to each other. Each of the extremity ends of the column-like magnets 20x, 20y forms a convex surface.</p> |
