PROBLEM TO BE SOLVED: To provide the lubricating device of a vehicular engine which can control lubricating an amount of lubricating oil precisely according to an engine speed. SOLUTION: A valve opening period t1 of a solenoid valve is made longer than a nondelivery period t3 of an oil pump, and shorter than a delivery cycle T2 regardless of an engine speed which is the delivery cycle T2 of the oil pump. The valve opening period t1 of the solenoid valve is made not longer than the delivery cycle T2 of the oil pump, and the valve opening cycle T1 of the solenoid valve is made not shorter than the oil delivery period t2 of the oil pump by this controlling, so that the valve opening period t1 of the solenoid valve can always overlap the oil delivery period t2 .
