Abstract
Helical gears in gear trains of speed reducers generate thrust forces in directions not to separate a speed reducer casing which has an axial three-piece structure, whereby leakage of lubricant oil from between separated surfaces in the speed reducer casing is prevented. Output gear which generates large thrust force on the final stage in each gear train of the speed reducers both generated inward forces, so that the center casing does not receive forces in directions in which the left and the right casings is separated therefrom.
