Zusammenfassung:A rolling bearing device includes: an outer ring that has outer ring raceway grooves formed on an inner peripheral surface of the outer ring and a counter bore portion that is provided on an outer side of the outer ring raceway grooves in an axial direction; an inner ring member that has inner ring raceway grooves formed on an outer peripheral surface of the inner ring member; and a plurality of rolling elements that are interposed between the outer ring raceway grooves and the inner ring raceway grooves so as to freely roll and that are in contact with the inner ring raceway grooves of the inner ring member and the outer ring raceway grooves of the outer ring at a predetermined contact angle. A lubricant reservoir portion that stores lubricant is formed at a portion in the outer ring raceway grooves adjacent to the counter bore portion.
