To provide an elastomer bush with a pin, a railway vehicle truck and an elastic assembly which have excellence in vibration-proof characteristics, durable elastomer and easy exchangeability of elastomer.SOLUTION: First and second elastic assemblies 6A and 6B are constituted by vulcanizing the first and second elastomers to adhere not only to first and second inner cylindrical members but also first and second outer cylindrical members. The first and second elastomers are preliminarily compressed and made unable to be pulled out from a core shaft 5 as a result of fitting the first and second elastic assemblies 6A and 6B to the core shaft 5 and then containing the assemblies and the shaft in an annular case 7 to make tapered ring parts 612A and 612B of the first and second cylindrical members 61A and 61B touch first and second tapered parts 512A and 512B of the core shaft 5.SELECTED DRAWING: Figure 4

    【課題】防振性能及び弾性体の耐久性に優れ、弾性体の交換が容易なピン付き弾性体ブッシュ、鉄道車両用台車、及び、弾性組立部品を提供すること。【解決手段】第1及び第2弾性体を第1及び第2内側筒部材と第1及び第2外側筒部材に加硫接着することにより第1及び第2弾性組立部品6A,6Bを構成し、第1及び第2内側筒部材61A,61Bのテーパ付きリング部612A,612Bを心軸5の第1及び第2テーパ部512A,512Bに当接させるように第1及び第2弾性組立部品6A,6Bを心軸5に装着して環状ケース7に収容することにより、第1及び第2弾性体を予圧縮し、心軸5から抜けないようにする。【選択図】図4
