Abstract
The present invention provides a member, for a resin-made rolling bearing, which has a low extent of a moisture absorption-caused change in its dimension and mechanical properties, keeps sufficiently high mechanical properties after the member absorbs moisture, and is excellent in its resistance to hydrolysis, grease deterioration, and heat and also provides the rolling bearing in which the member for the rolling bearing is used. A rolling bearing () has an inner ring (), an outer ring (), a plurality of rolling elements () interposed between the inner ring () and the outer ring (), a crown-shaped cage () for retaining the rolling elements (), and a seal () covering an opening disposed at a gap between the inner ring () and the outer ring (). The cage () and the seal () are moldings of a resin composed of polyphthalamide resin.
