摘要： A rotation transmitting apparatus comprises a first sun gear (3) joined to a first shaft (1) so as to rotate interlockingly, a second shaft (2) arranged to the first shaft (1) coaxially, a second sun gear (4) joined to the second shaft (2) so as to rotate interlockingly, a first planetary gear (5) meshed with the first sun gear (3), a second planetary gear (6) rotating with the first planetary gear (5) and meshed with the second sun gear (4), and a carrier (7) supporting the first and second planetary gears (5) and (6) and arranged to be driven by a differential electric motor (10). In particular, the number of teeth of each of the first and second sun gears (3) and (4) and the first and second planetary gears (5) and (6) is determined so that the ratio of a torque applied to the second shaft (2) to a torque applied to the first shaft (1) ranges from 1:0.7 to 1:0.9.
