Abstract
A non-contact power generator includes: a magnet disposed at a distance to a main surface of a moving body that moves in one direction and the opposite direction, and the magnet generating a magnetic flux passing the main surface; a coil being separated from a surface of the magnet that faces away from the main surface, the coil being linked with the magnetic flux from the magnet; and a magnetic flux guide member disposed in a part of a magnetic path of the magnetic flux linked with the coil. The magnet is moved along the shaft in the moving direction of the moving body at a speed lower than the speed of the moving body by a reaction force acting on the magnet on a basis of eddy currents generated in the main surface in such a direction as to hinder a change of the magnetic flux from the magnet.
