Yes.

  The projecting piece material 47 made of magnetic material and the projecting piece material 48 made of nonmagnetic material are laminated and arranged on the lower edge portion 42 d of one plate material 42 so as to protrude in a direction perpendicular to the plate material 42. The protruding piece material 47 is disposed at a position closer to the circular surface 21 a of the fixed magnet 21 than the protruding piece material 48. In the plate members 41 and 42 and the sheet magnets 43 and 44, through holes 41x, 42x, 43x, and 44x are formed in portions that sandwich the plurality of disk magnets 46, 46, and 46, respectively.

  In the magnetic device 100 shown in FIGS. 1 and 2, when an initial external force in the same direction as the moving directions D1 and D2 is applied to the movable magnet portions 31 and 32, the movable magnet portions 31 and 32 move in the moving direction along the tracks R1 and R2. While moving to D1 and D2, the magnetic force approaching region of the fixed magnet unit 20 is approached. In this approaching process, the magnetic pole 31a (N) of the movable magnet section 31 is attracted to the magnetic poles (S) of the plurality of stacked disk-shaped magnets 45, and the magnetic pole 32a (S) of the movable magnet section 32 is circular. Since it is attracted to the magnetic pole (N) of the plate magnet 45, the urging forces in the moving directions D1 and D2 are applied to the movable magnet portions 31 and 32, respectively.

  The movable magnet portions 31 and 32 to which the urging force from the plurality of disk-shaped magnets 45 is applied approach the fixed magnet 21 along the tracks R1 and R2, but the inner peripheral movable magnet portion 32 is The magnetic pole 32 a (S) is attracted by the magnetic pole (N) of the circular surface 21 a of the fixed magnet 21, and an urging force is further applied. In this process, the projecting piece members 47 and 48 promote the attractive force from the fixed magnet 21 to the movable magnet portion 32. Further, the plate members 41 and 42 and the sheet-like magnets 43 and 44 increase the urging force in the moving directions D1 and D2 with respect to the movable magnet portions 31 and 32, respectively, and the repulsive force (the urging force in the direction opposite to the moving directions D1 and D2). ).

  When the movable magnet portions 31 and 32 enter the magnetic force affected area of the circular surface 21 a of the fixed magnet 21, they are attracted and biased by the tubular body 23 and the columnar magnet 22, and pass through the vicinity of the axis 21 c of the fixed magnet 21. Then, it enters the magnetic force-affected region of the plurality of laminated disk-shaped magnets 46 as it is.

  When the movable magnet portions 31 and 32 enter the magnetic force affected region of the plurality of disk-shaped magnets 46, the movable magnet portion 31 on the outer peripheral side has a magnetic pole 31 a (N) from the magnetic pole (N) of the disk-shaped magnet 46. In response to the repulsive urging force, the movable magnet portion 32 on the inner peripheral side receives a repulsive urging force from the magnetic pole (S) of the disk-shaped magnet 46 at its magnetic pole 32 a (S). As a result, a strong biasing force toward the moving directions D1 and D2 is given to the movable magnet portions 31 and 32, and the movable magnet portions 31 and 32 move in a direction away from the fixed magnet portion 20 along the tracks R1 and R2. . Thereafter, the movable magnet portions 31 and 32 continue to move in the moving directions D1 and D2 along the circular tracks R1 and R2 for a long period of time without applying an external force.

  As described above, in the magnetic device 100, the movable magnet units 31, 32 move from the fixed magnet unit 20 to the movable magnet units 31, 32 by moving along the tracks R1, R2 within the magnetic force affected region of the fixed magnet unit 20. Since the urging force in the moving directions D1 and D2 is applied to 32 and the movable magnet portions 31 and 32 continue to move in the moving directions D1 and D2 along the circular orbits R1 and R2 without applying external force, they rotate. The arm 33 continues to rotate in the clockwise direction in FIG. 1 for a long period of time. For this reason, the magnetic device 100 exhibits a motion maintaining function superior to that of the conventional magnetic device.

Since it is attracted by the magnetic pole (N) of 56a, smooth urging forces in the moving directions D1 and D2 are applied to the movable magnet portions 31 and 32, respectively.

  When the movable magnet portions 31 and 32 pass through the magnetic force affected region of the circular surface 21a of the fixed magnet 21 and enter the magnetic force affected region of the plurality of disc-shaped magnets 55b and 56b, the outer peripheral movable magnet portion 31 is The magnetic pole 31a (S) receives a repulsive urging force from the magnetic pole (S) of the disk-shaped magnet 56b, and the movable magnet portion 32 on the inner peripheral side has a magnetic pole 32a (S) of the magnetic pole of the disk-shaped magnet 56b ( Receives a repulsive force from S). As a result, a strong biasing force toward the moving directions D1 and D2 is given to the movable magnet portions 31 and 32, and the movable magnet portions 31 and 32 move in a direction away from the fixed magnet portion 25 along the tracks R1 and R2. . Thereafter, the movable magnet portions 31 and 32 continue to move in the moving directions D1 and D2 along the circular tracks R1 and R2 for a long period of time without applying an external force.
