<p>A planetary gear device having a novel planetary gear mechanism, the device being capable of solving problems of conventional devices. A planetary gear coaxially integrally has at least two, first and second gears (B, E) having different numbers of teeth. One of sun outer gears or sun inner gears having two fundamental axes has at least two, third and fourth gears (C, F) capable of respectively meshing with the first and second gears (B, E) of the planetary gear and of rotating relative to each other. The ratio of the numbers of the teeth of the first gear (B) and the third gear (C) is different from the ratio of the numbers of the teeth of the second gear (E) and the fourth gear (F). The other of sun outer gears or sun inner gears having one fundamental shaft coaxially integrally has at least two, fifth and sixth gears (A, D) respectively meshing with the first and second gears (B, E). The ratio of the numbers of the teeth of the first gear (B) and the fifth gear (A) is the same as the ratio of the numbers of the teeth of the second gear (E) and the sixth gear (D).</p> |
