PURPOSE:To obviate the necessity for a complicated mechanism while transmission torque can be uniformly distributed further while a gear in light weight such as helical gear can be used, though lightening the weight with compactness. CONSTITUTION:A pair of the first/second pinions 31, 32 are meshed with a gear wheel 9, to provide the first/second helical gear wheels 35, 36 in the upper or lower of each shaft of the first/second pinions, and an outer cylinder 40, in which the first/second helical pinions meshed with these first/second helical gear wheels are fixed to the upper or lower, is spline fitted to an input shaft. In this way, torque is uniformly distributed by moving the outer cylinder. |
