<p>PROBLEM TO BE SOLVED: To provide a rotation acceleration device having a simple structure capable of preventing a high price of manufacturing cost, reducing energy used for rotating a body to be rotated and reducing a consumption cost of energy.SOLUTION: This invention comprises a plate-like rotating body 24 rotatably arranged around an axis line extending in a horizontal direction; a center-fixed sprocket 22 arranged on the same axis line as that of the rotating body 24 so as not to be self-rotated and turned around; a plurality of outer sprockets 28 capable of turning around and self-rotating around the same axial line under rotation of the rotating body 24; a roller chain 32 for driving the outer sprockets 28 to rotate in such a way that the outer sprockets 28 may not produce any relative rotation in respect to the center-fixed sprocket 22; a rotating body 26 arranged to cooperate with the rotating body 24; and a plurality of supporting members 34, 36 having mass bodies 38, 40 arranged at the other end in a longitudinal direction in such a way that they are displaced in a direction where the rotating forces of the rotating body 24 and the rotating body 26 are increased.</p> |
