The purpose of the present invention is to achieve a rubber bushing for a railway bogie having a novel structure, the rubber bushing being capable of improving flame retardancy and the like against flames and the like that are impacted from the outside, without significantly compromising the basic characteristics required for input vibrations and loads. A rubber bushing (10) used in a bogie of a railway vehicle is formed by connecting a shaft-shaped inner member (12) and an outer member (14) disposed apart from the outer peripheral side of the inner member (12) with a rubber elastic body (16), and a cover section (48) is provided at the axial end of the rubber elastic body (16) by means of a member separate from the rubber elastic body (16). And a covering section (48) that covers an exposed end section surface (44) of the rubber elastic body (16), said exposed end section surface (44) being exposed to the outside between the axial end sections of the inner member (12) and the outer member (14), from the outside.

    实现一种新型结构的铁路转向架用橡胶衬套,其能够在不大幅损害针对所输入的振动、载荷而要求的基本特性的情况下,实现针对从外部波及来的火焰等的阻燃性等的提高。在铁路用车辆的转向架中使用的橡胶衬套10是利用橡胶弹性体16将轴状的内侧构件12和在该内侧构件12的外周侧分离配置的外侧构件14连结而成的,其中,在所述橡胶弹性体16的轴向端部,通过相对于该橡胶弹性体16独立的构件设置有覆盖部48,所述覆盖部48从外侧将该橡胶弹性体16在所述内侧构件12与所述外侧构件14的各轴向端部之间露出于外部的端部露出面44覆盖。
