Abstract:
1. A rotation device comprising a rotatable output axis arranged to have its axis line extending in a horizontal direction perpendicular to the direction of gravity, a plurality of shafts each having one end attached to said output axis, a plurality of first heavy weights each supported on the other end of said shafts, a first heavy weight guide member shaped in a cylinder for slidably supporting said plurality of first heavy weights, second heavy weights supported slidably by and along the respective shafts at a position nearer said output axis in relation to said first heavy weights, and an eccentric guide member for supporting slidably said second heavy weights to make the rotational orbit of said second heavy weights associated with the rotation of said output axis eccentric to the axial center of said output axis, said first heavy weight guide member being formed in a substantially perfect circle ring so as to allow said first heavy weight to move along the circumference of said first heavy weight guide member.
