POWER TRANSMISSION

摘要

Disclosed is a power transmission which comprises: a catch tank (80); an oil path (82) which supplies lubricant from the catch tank (80) to a bearing (62a); a top part (21b) which receives lubricant raised by a differential ring gear (65) and guides the lubricant to the catch tank (80); and an oil path (84) which guides lubricant discharged from an oil pump to the catch tank (80). It is therefore possible to prevent shortage of lubricant supplied to the bearing (62a) even when the amount of lubricant that is raised by the differential ring gear (65) and reaches the catch tank (80) by way of the top part (21b) is small or the amount of lubricant that is discharged from the oil pump and is guided to the catch tank (80) by the oil path (84) is small.
