A final gear box accommodates a pinion gear and a bevel gear in a rotatable manner and contains an oil. A recess is provided at a downstream end of a drive shaft. The recess and the upstream end of the pinion gear shaft portion are splined coupled with each other so that the drive shaft and the pinion gear can be rotated together and relatively moved in an axial direction. A space permitting relative movement between the drive shaft and the pinion gear is provided between the pinion gear and the recess. The pinion gear is provided with a hollow portion which pierces the pinion gear in the axial direction and conducts oil to the space portion.
