PROBLEM TO BE SOLVED: To reduce the number of parts items of a rolling bearing, to shorten the whole of an engine by shortening a space in the axial direction, and to reduce weight of the engine. SOLUTION: Since both sides of an inner ring 3A of the rolling bearing 2 are formed with radial scoops 6A and 7A for taking the lubricating oil injected from nozzles 8 and 9, the number of parts items of the bearing 2 is reduced to shorten the assembling time. Since width L<SB>2</SB>of the inner ring 3A is formed shorter than a total L<SB>1</SB>of width of a current inner ring 3 and width of the lubricating oil taking radial scoops provided in both sides of the inner ring 3, a space in the axial direction can be shortened, and length of the whole of the engine is shortened to reduce weight of the engine.
