Summary:PROBLEM TO BE SOLVED: To provide an inner ring capable of lengthening the service life of a roller bearing, and manufacturing in a cost effective manner. SOLUTION: The inner ring 1 has a rolling body raceway surface 2 present in the axial direction of the rotary shaft 12 of the inner ring 1 between two edge ends 5, 6 of the inner ring 1. The inner ring 1 has sunken parts 7, 8 between at least one edge end 5, 6 and the rolling body raceway surface 2. More specifically, the roller bearing which rotates at a high speed is lengthened in the service life by improving a lubricating state, can be simply manufactured in a cost-effective manner, and can be used in place of a conventional inner ring without additionally changing the roller bearing. The widths a, b of part between both contact surfaces 3, 4 in the sunken parts 5, 6 are set to 15 to 30% of the interval c of both contact surfaces 3, 4. COPYRIGHT: (C)2010,JPO&INPIT
