ABSTRACT:
A lubricating device for a motor vehicle including (a) a power transmission system having rotating members which are all at rest upon stopping of the vehicle, (b) a casing accommodating the power transmission system and storing a lubricating oil, and (c) an oil pump which is driven by the power transmission system and which operates to deliver the oil from the bottom portion of the casing to lubricating points of the power transmission system. An oil reservoir is provided to store a predetermined amount of the oil delivered by the pump, when a delivery amount of the pump exceeds a predetermined value with an increase in the speed of the power transmission system. A bath of the lubricating oil stored in the bottom portion of the casing has a first oil level when no oil is stored in the reservoir such that a portion of the power transmission system is immersed in the bath of the lubricating oil, and a second oil level when the predetermined amount of the oil delivered by the pump is stored in the reservoir such that the lower end of the power transmission system is located above the second oil level.
