<P>PROBLEM TO BE SOLVED: To provide a rolling bearing superior in lubricity even when lubricated by a small quantity lubricating method. <P>SOLUTION: A cage of the rolling bearing lubricated by the small quantity lubricating method is composed of substantially concentrically arranged and diametrically different two annular members 4A and 4B. The inside annular member 4B is composed of a plurality of resin plate-like members 7, 7, etc. having a pocket capable of rollingly holding a rolling body 3 and curved along an inner ring 1 and an outer ring 2. The plate-like members 7 are curved along the inner ring 1 and the outer ring 2, and its radius of curvature is set smaller than a radius of the outside annular member 4A. Thus, a width of a clearance between the annular member 4A and the annular member 4B becomes nonuniform in the peripheral direction. That is, the clearance becomes large for separating in the peripheral direction from a contact part of the annular member 4A and the annular member 4B. <P>COPYRIGHT: (C)2007,JPO&INPIT |
