Description of the Related Art As a conventional lubricating means, various gear elements are used to store a hydraulic pressure supply source such as an oil pump and an oil stored in a lower part of a case for accommodating a transmission that adapts engine characteristics and power performance required by a vehicle. It is known that the oil is stirred by the above method and the scraped oil is supplied as lubricating oil to each lubricating portion.

する方法では完全に潤滑を行うことができない。A differential gear such as a differential gear is added to the hydraulic pressure supply source and the transmission, and the transaxle housed in a common case has a main shaft portion for disposing the transmission and a differential gear. This is a three-axis configuration consisting of the sub-shaft to be placed and the intermediate shaft to place the idler gear. With such multiple axes, the structure is further complicated, and the method of supplying scraping oil as lubricating oil to each lubrication unit is perfect. Cannot be lubricated.
