Rolling bearing

A rolling bearing, comprising:

• an inner ring;
• an outer ring that is arranged on an outer periphery of the inner ring via a plurality of rolling elements;
• a retainer that retains the plurality of rolling elements at regular intervals in a circumferential direction of the retainer;
• and
• a sealing member that is arranged in an annular space formed between the inner ring and the outer ring, and that seals a lubricant inside the rolling bearing,
• wherein a first lubricant reservoir portion that stores the lubricant is formed on a radially inner side of the retainer,
• wherein a second lubricant reservoir portion that stores the lubricant is formed on an inner side of the sealing member,
• wherein a third lubricant reservoir portion that gores the lubricant is formed in an inner peripheral surface of the outer ring, at a position near a raceway on which the plurality of rolling elements roll,
• wherein an inclined first guide surface that guides the lubricant from the second lubricant reservoir portion toward the raceway is formed in an inner surface of the sealing member, and an inclined second guide surface that is in-line with the first guide surface and that guides the lubricant toward the raceway is formed in the inner peripheral surface of the outer ring, and
• wherein the first lubricant reservoir portion of the retainer is in communication with pockets of the retainer, which accommodate the plurality of rolling elements.
