PROBLEM TO BE SOLVED: To eliminate the constraint of a maintenance cycle attributable to grease and enable the grease to stably lubricate a bearing, in the rolling bearing of a grease lubricating type. SOLUTION: A recessed step 2b is formed at the side of the raceway surface 2a of an outer ring 2 and a ring-shape grease reservoir member 7 with a grease reservoir recessed part 7a formed on an outer diameter surface is fit in the recessed step 2b. A grease passage 9 for communicating from the grease reservoir recessed part 7a to the inside of the bearing is formed between the grease reservoir member 7 and the outer ring 2. The grease A can be stably and continuously supplied from the grease reservoir recessed part 7a into the bearing by supplying the grease A from an external grease supply device 11 to the grease reservoir recessed part 7a, and thus, the constraint of the maintenance cycle attributable to the grease is eliminated and stable lubrication in the bearing is attained.
