Abstract
An oil supply device includes an axial oil passage and an intersecting oil passage provided in a propeller shaft, an axial oil passage and an intersecting oil passage provided in a drive shaft, and an oil guide passage. The intersecting oil passages allow oil inside the axial oil passages to be spouted radially of the shaft by centrifugal force generated as the shafts rotate. The oil is then supplied via the oil guide passage to an intermediate speed reduction device. As a result, it is possible to sufficiently lubricate an intermediate speed reduction device mounted on a drive shaft through a simple and compact arrangement.
