<P>PROBLEM TO BE SOLVED: To provide a rolling bearing device with a grease vessel that can stably and surely supply the base oil of grease to a raceway surface of a fixed-side raceway ring. <P>SOLUTION: The grease vessel 2 which is attached in a bearing space and accumulates the grease inside is position-fixedly arranged at an outer ring 3. An annular inclined oil guide surface 8a having an inclination approaching the bottom of the raceway surface 3a as it approaches the raceway surface 3a is formed along the edge of the raceway surface 3a of the outer ring 3 of a rolling bearing 1. A gap formation piece 12 which extends in the axial direction, whose tip 12a is positioned in the vicinity of the inclined oil guide surface 8a, and in which a gap for oozing out the base oil of the grease in the grease vessel 2 is formed at the tip 12a is arranged at the grease vessel 2. <P>COPYRIGHT: (C)2012,JPO&INPIT |
