ABSTRACT:
A planetary gear device includes a sun gear, planet gears to be meshed with the sun gear and an internal gear to be meshed with the planet gears each having a tooth profile formed to an involute curve, wherein tooth surfaces on one side of the planet gears meshing with the sun gear and tooth surfaces on the other side of the planet gears meshing with the internal gear are respectively corrected by different amounts of correction on the basis of deformation amounts of teeth of the planet gears caused by meshes with the sun gear and the internal gear so that rotary motion can be smoothly transmitted when the tooth faces of the planet gears meshed with the sun gear and the tooth faces of the planet gears meshed with the internal gear are elastically deformed by the mesh thereof.
