PURPOSE: To convert the magnetic energy of permanent magnets into kinetic energy and utilize the kinetic energy by arranging both poles of another permanent magnet onto the surface of a pole of the fixed permanent magnet in a manner that both poles can be brought near the surface vertically or obliquely.

CONSTITUTION: A permanent magnet in which the surface of the permanent magnet having the same shape and the same magnetic force is used as an N pole is employed as a stator 1, and a permanent magnet in which the surface is used as a S pole is employed as a stator 2. Permanent magnets capable of being separately moved are used as moving elements 3, and both poles of the moving elements 3 re regulated so as to be brought near and shifted vertically or obliquely on the surfaces of the stators 1, 2 by employing rails 4, etc. The moving elements 3 receive magnetic action with the stators 1, 2 and are moved in the predetermined direction.
