Efficient rotation substantially free of collision-type noises is enabled in a rotation drive device for rotating a rotating body by means of changes in weight balance. Provided is a rotation drive device (1) having a rotating body (5) capable of rotating about a point (O), a rotation detection means (6) capable of detecting the rotating state of the rotating body (5), six rotation weight devices (7a to 7f) attached to the rotating body (5), and a power generation device (8) for generating power using the rotation of the rotating body (5), each of the rotation weight devices (7a to 7f) being provided with a rotating arm (10) rotatably and axially mounted in positions of six-point symmetry about the point (O) within the rotating body (5), a motor (11) for rotating the rotating arm (10) at the same speed as the rotating body (5) but in the opposite direction, and a weight (12) provided to the free-end side of the rotating arm (10), all of the rotation weight devices (7a to 7f) being controlled by the motors (11) so that the rotating arms (10) face toward the same side, and the rotating body (5) being rotated by the weight balance centered about the point (O) of the weights (12) of all of the rotating arms (10). |
