Title:
MAGNETIC FORCE DEVICE
Document Type and Number:
Japanese Patent JP2019019777
Kind Code:
A
Abstract:
To provide a magnetic force device that exhibits a more superior motion maintenance function than a conventional magnetic force device.SOLUTION: A magnetic force device 100 includes a stationary magnet part 20, and movable magnet parts 31, 32 capable of moving along paths R1, R2 in a magnetic force effect region. The stationary magnet part 20 includes: a stationary magnet 21; a cylindrical magnet 22 and a tubular body 23 made of a magnetic material; plate materials 41, 42 made of two magnetic materials; sheet-like magnets 43, 44 attached to outside surfaces 41a, 42a of the plate materials 41, 42; disc-shaped magnets 45, 46 held between the plate materials 41, 42; and protrusion materials 47 made of the magnetic materials and protrusion materials 48 made of the non-magnetic materials arranged in the lower edge 42d of the plate material 42. Magnetic poles 31a, 32a of the movable magnet parts 31, 32 are arranged in the diagonally projecting conditions toward respective moving directions D1, D2. A polarity of a circular surface 21a of the stationary magnet 21 and a polarity of a magnetic pole 31a of one movable magnet 31 are set to the same N pole.SELECTED DRAWING: Figure 1
