Provided is a bearing having a plurality of rolling elements disposed between an inner ring and an outer ring that are disposed coaxially, wherein a groove section extending in a circumferential direction of an outer circumferential surface of the outer ring outside in a radial direction is formed on the outer circumferential surface, and an enveloping layer formed of any one of rubber, a thermoplastic elastomer and a plastic is formed on the outer circumferential surface.

Rolling bearing

A structure includes an enveloping layer formed on one of a circular outer surface or a flat outer surface having irregularities, wherein the enveloping layer includes an outer circumferential surface layer formed by thermally fusing a thermoplastic elastomer. The enveloping layer has a first material layer provided on one of the outer surfaces and formed from an amorphos plastic, and a second material layer provided on the first material layer and formed from a thermoplastic elastomer selected from the group consisting of styrenes, olefins, polyvinyl chlorides, urethanes and polyesters.
