PROBLEM TO BE SOLVED: To obtain continuous rotational motive force by surely obtaining reciprocating motion of a piston magnet and improving continuity of the motion.SOLUTION: A rotational motive force generation device 100 includes first and second piston magnet members 60 and 61 and a crankshaft 11 and also includes first and second guide members 50 and 51, first and second stationary magnet members 70 and 71 and first demagnetization belts 30 and 130. The first and second piston magnet members 60 and 61 and the first and second stationary magnet members 70 and 71 are disposed in such a manner that upper pole surfaces 60a and 61a having an equal polarity and stationary pole surfaces 70a and 71a are opposite to each other. The first and second demagnetization belts 30 and 130 include a demagnetization magnet part 38 having magnetic force of a different polarity from the upper pole surfaces 60a and 61a, the magnetic force being weaker than the magnetic pole of the upper pole surfaces 60a and 61a, and a non-magnetic-force part 39. |
