A lubricating system for an internal combustion engine, comprising:an oil passage extending from an oil pump to a discharge port in an internal combustion engine is branching into at least two branched oil passages; and one of said at least two branched oil passages is provided with a first restricting portion having a diameter smaller than a diameter of said one of said at least two branched oil passages, said first restricting portion for restricting a flow amount of oil, and a bypass valve which acts, when a hydraulic pressure in said oil passage exceeds a specific value, to divert a portion of the oil to a second restricting portion so as to increase the flow of oil, wherein a continuously variable transmission is driven by hydraulic pressure of the oil from another of said at least two branched oil passages.
