PURPOSE:To obtain a rotary force with a simple structure by converting attracting and repelling forces alternately operating between poles into rotary motion by a crank mechanism and a planetary gear mechanism. CONSTITUTION:A magnet 3 is rocked between magnets 2, planetary gears 11 rotate around their own axes around a sun gear 15 to accumulate winding repelling forces of springs 9 provided at both ends of the magnets 2. Whenever the magnets 3 approach the magnets 2, the magnets 2 are intermittently rotated at every half rotation by the operation of the springs 9 to alternately vary the direction of the poles. At this time, since a ring 21 is provided at the gears 11 which rotate around the sun gear 15 while rotating around it own axis, the magnets 2 are always constant at the period that intermittent rotation occurs. |
