A lubricating device for a motor vehicle including (a) a power transmission system (16, 18, 38, 40) having rotating members which are all at rest upon stopping of the vehicle, (b) a casing (14) accommodating the power transmission system and storing a lubricating oil, and (c) an oil pump (46) 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, wherein an oil reservoir (52) 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, and the level (A) of the oil stored in the bottom portion of the casing when no oil is stored in the reservoir is determined such that a portion of the power transmission system is immersed in the bath of the lubricating oil, and the oil level (B) when the predetermined amount of the oil delivered by the pump is stored in the reservoir is determined such that the lower end of the power transmission system is located above the oil level (B). <MATH> |
