To provide an apparatus for converting a suction force and a reaction force between magnets into a rotational force, rotating a power generator and for obtaining power.

The magnetic force rotary power generating apparatus is used for an electric vehicle, and an industrial power supply, a home power supply and an agricultural power supply. Bevel gears 3 are attached to lower parts of a main disc 1 and of a sub disc 2. The outer circumference is divided into two sections on surfaces of the main disc 1 and on the sub disc 2. Magnets 4 have magnetic poles protruding at ends and inclined magnetic pole faces and are arrayed so as to align the same magnetic pole and fixed at sectional points of the main disc 1 on an incline line e in the same direction. Magnets 5 have magnetic poles protruding on a back side and inclined magnetic pole faces and are arrayed so as to align the same magnetic pole and fixed at sectional points of the sub disc 2 on the incline line e in the same direction. The upper main disc 1 and the sub disc 2 are attached to and fixed by a support frame 17. A main disc rotator 12 and a sub disc rotator 13 are formed by attaching central shafts 8 and are supported by the bearings of a placement container 15. The bevel gears 3 are engaged at a location with the sectional point of the sub disc 2 displaced farther from the sectional point of the main disc 1 on the magnetic pole face side. The shaft of the power generator 14 provided outside an apparatus container 16 and the central shaft 8 of a main disc rotational wheel 12 are coupled by a coupling 21.
