<p>PURPOSE:To obtain a driving force free of noises and environmental pollution, by turning an output shaft by making magnetic force acted between two magnets operative and inoperative intermittently and moving a permanent magnet of a movable weight type upward and downward by the magnetic attractive force and the weight of itself. CONSTITUTION:Since the magnetic attractive force is produced by an electromagnet 20 when a movable weight type permanent magnet 2 is located at the lower dead point, an iron piece 17 is slided to the left by the force of a spring 19 and the movement of the iron piece 17 is transmitted to a shield plate 8 via a lever 11, so that the shield plate 8 is retracted from between two magnets 1 and 2. Resultantly, the permanent magnet 2 is moved upward by the magnetic attractive force exerted between the two magnets 1 and 2 and the force is transmitted to an output shaft 3 via a crank mechanism 5, so that the output shaft 3 is set into rotation. Thus, it is enabled to take out a driving force free of noises and environmental pollution.</p> |
