摘要： A rolling bearing includes: an inner ring; an outer ring; a plurality of rolling elements; a retainer; and a sealing member. First to third lubricant reservoir portions that store the lubricant are respectively formed on the radially inner side of the retainer, on the inner side of the sealing member, and in an inner peripheral surface of the outer ring at a position near a raceway. 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. An inclined second guide surface contiguous with the first guide surface and guiding the lubricant toward the raceway is formed in the inner peripheral surface of the outer ring. The first lubricant reservoir portion of the retainer is in communication with pockets of the retainer, which accommodate the rolling elements.

摘要： A ball screw device comprises a screw shaft, a nut externally mounted on the screw shaft, and a multiplicity of balls interposed between thread grooves of the screw shaft and the nut. The screw shaft has a ball circulation groove for coupling downstream and upstream sides of the thread groove so that the balls are returned from the downstream side to the upstream side and thereby circulated in the thread groove of the screw shaft. The ball circulation groove has such a curved shape as to sink radially inward in an intermediate region in a rolling direction of the balls and has a curved shape protruding radially outward in both end regions, and is configured in the manner that the centrodes of the balls rolling in the both end regions and the balls rolling in the thread groove of the screw shaft satisfy predetermined conditions with respect to circulation of the balls.
