PURPOSE:To reduce the cost without necessity of natural resources as a power source by utilizing a magnetic force as the power source, separably contacting the both ends of a stator and a movable element with a magnetic unit to reciprocate a magnet. CONSTITUTION:A motive power device 2 has a stator 4 made of a permanent magnet, a movable element 6 similarly formed, and a magnetic unit 8 made of iron or the like. A cranking mechanism 10 connected with the element 6 for converting the reciprocating motion into a rotary motion is provided. When the device 2 is operated, the unit 8 is contacted from approaching direction (in the direction of an arrow Y1) with both ends 4a-6a of the opposed stator 4 and the element 6. Thus, a demagnetizing phenomenon occurs between the stator 4 and the element 6 to lift the element 6 in the direction of an arrow X1. Further, when the unit 8 is moved in opposite direction to the arrow Y1, a repelling force is generated between the stator 4 and the element 6 to drop the element 6, and converted to a rotary motion through the mechanism 10. |
