Abstract
A rolling bearing cage made of an elastic material comprising an annular member having a plurality of circumferentially spaced pockets for rolling elements, confronting terminal end portions, at least one shoulder projecting in a peripheral direction from at least one of the terminal end portions adapted to engage the opposing terminal end portion under pre-tension, at least one recess in at least one of the terminal end portions adjacent the shoulder and extending inwardly from the side edge of the annular member so that the lug member functions in the nature of a leaf spring having limited pivotal movement in a peripheral direction. In this fashion the cage has elastic resilience within a relatively wide range in a peripheral direction without unduly overstressing the cage material.
