Claim:
1. A cage for a rolling bearing, comprising: the cage being formed of a polymer and being adapted to circumferentially space a row of rolling elements, the cage defining a plurality of pockets for the row of rolling elements and also defining a plurality of connecting portions, each of the plurality of connecting portions connecting two associated successive pockets, wherein at least one of the plurality of connecting portions is elastically deformable at least in a circumferential direction so as to allow the two associated successive pockets to move relative to one another in the circumferential direction during operation of the rolling bearing, each of the plurality of pockets having first and second portions that each extend from a base portion thereof and each form a free end, the first and second portions being spaced in the circumferential direction, each of the plurality of connecting portions are connected to the first portion of one of the two associated successive pockets and is also connected to the second portion of the other of the two associated successive pockets, the at least one of the plurality of connecting portions attaches to a location of each of the first and second portions that is between the free end and the base portion such that the at least one connecting portion does not attach or extend from the free end of the first and second portions, each of the plurality of connecting portions forms a V-shape in cross section, and wherein a first longitudinal axis of each one of the plurality of connecting portions is not parallel to a second longitudinal axis of the first portion and is not parallel to a third longitudinal axis of the second portion of the two associated successive pockets.
