Zusammenfassung:	PROBLEM TO BE SOLVED: To prevent the deterioration in sealability in a cold state, while restraining excessive lubricating oil supply to an engine, in a lubricating device of the engine. SOLUTION: In S1, various signals are read in, and when, in determination in S2 and S3, a detection result of an Ig sensor 53 is OFF and a detection result of the Ig sensor 53 of the last time is ON, whether or not a forced opening condition of an OCV30 is realized is determined in S4. In the S4, when both the intake temperature and the engine water temperature are low, forced opening is performed by turning off an electric current of the OCV30, and oil is supplied to an operation chamber 5 by increasing oil supply pressure (S5), and operation is advanced to the next S6. When a predetermined time passes, feedback control of system hydraulic pressure of S7 is performed, and whether or not the predetermined time t2 passes is determined in S8, and when a condition is satisfied, the operation is advanced to S9, and the feedback control of the system hydraulic pressure is finished, and is returned to a start.
