Zusammenfassung:	PROBLEM TO BE SOLVED: To improve fuel economy by reducing a friction loss in a sliding portion of a crankshaft 7 by speedily elevating a temperature of a lubricating oil 6.SOLUTION: A heat pipe 28 is provided over a water jacket 17a of a cooling water passage 17 and a main supply passage 16A of a lubricating oil supply passage 16. When the temperature of cooling water W in the water jacket 17a is elevated in warming-up of an engine, the temperature of a lubricating oil 6 in the main supply passage 16A is elevated speedily via the heat pipe 28. The temperature elevated lubricating oil 6 is then supplied to a journal part 7A and a pin part 7B of a crankshaft 7 via branch passages 16B.
