Abstract
A cage that contributes to smooth operation of a rolling guide unit and said rolling guide unit itself are provided. Projections are formed continuously between each of a plurality of openings, arranged in a row for insertion of rolling elements, that prevent rolling elements from coming out of those openings, thereby increasing the rigidity of the cage to prevent warping. The openings are provided with different sized diameters on opposite sides of the cage. On a given side, larger and smaller diameters alternate.
