Abstract: 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.

Abstract: An enveloping layer-coated slide bearing includes a slide bearing having a bearing surface formed in a cylindrical shape, and a first enveloping layer composed of a thermoplastic elastomer formed on and directly contacting an outer circumferential surface of the slide bearing. In another arrangement, a second enveloping layer is interposed between the first enveloping layer and the slide bearing and directly contacts the outer circumferential surface of the slide bearing.

Abstract: A method of manufacturing an enveloping layer-coated slide bearing includes preparing a slide bearing formed of polycarbonate, ABS resin, or an alloy material of the polycarbonate and the ABS resin; and forming an enveloping layer by injection molding a thermoplastic elastomer on an outer circumferential surface of the slide bearing. In an alternate method, an inner enveloping layer is formed directly on the outer circumferential outer surface of the slide bearing beneath the thermoplastic elastomeric enveloping layer.
