Abstract: PROBLEM TO BE SOLVED: To provide a sliding bearing device and an internal combustion engine, capable of reducing friction at operation starting.SOLUTION: An engine sliding bearing device 10 includes a heat exchanging section 50 capable of allowing oil to communicate between a bulkhead 21 and a bearing cap 22 of a cylinder block and a bearing metal 40, a lubricating oil supply passage 25 for communicating a main gallery 5 with the heat exchanging section 50, and a lubricating oil discharge passage 26 for communicating the heat exchanging section 50 with the outside. Thereby, oil supplied to the heat exchanging section 50 through the lubricating oil supply passage 25 at rotational motion of a crankshaft 30 is discharged from the lubricating oil discharge passage 26 at stopping of the rotational motion of the crankshaft 30, so that cooling efficiency of the bearing metal 40 is reduced. Consequently the friction at operation starting can be reduced because oil near the bearing can be quickly reduced in viscosity at starting of the upcoming rotational motion.
