An automatic rotating mechanism is described. The automatic rotating mechanism includes a main wheel, a first auxiliary wheel, a second auxiliary wheel, a movable heavy wheel, a gravitational rotating metal belt and an arrestor. The first auxiliary wheel is disposed above the main wheel, and the second auxiliary wheel and the movable heavy wheel are respectively disposed on both sides of the main wheel. The gravitational rotating metal belt includes a flexible metal connecting device and a plurality of heavy blocks on the outside of the flexible metal connecting device. The arrestor can move upward of the movable heavy wheel and the gravitational rotating metal belt. When the arrestor is removed from the gravitational rotating metal belt and the movable heavy wheel, the gravitational rotating metal belt and the movable heavy wheel drop a predetermined distance to generate kinetic energy to output a rotating power.
