To provide a railway vehicle center pin, a railway vehicle truck, and a method of manufacturing the railway vehicle center pin that can facilitate manufacturing process and secure sufficient mechanical strength.SOLUTION: A center pin 10 connects a vehicle body A of a railway vehicle and a truck frame 2 arranged below the vehicle body A. The center pin 10 includes a cylindrical main body part 30, a flange part 31 protruding more than an outer surface 30e of the main body part 30 at a lower end part 30c of the main body part 30, a stopper receiving part 32 connected to the outer surface 30e of the main body part 30 and receiving a stopper 18 for regulating the displacement of the main body part 30, and a damper receiving part 33 connected to the outer surface 30e of the main body part 30 and receiving a damper 19 for relaxing the vibration of the main body part 30. The main body part 30 and the flange part 31 form an integrally forged object. The stopper receiving part 32 and the damper receiving part 33 respectively form a forged object and the stopper receiving part 32 is welded to the outer surface 30e of the main body part 30.SELECTED DRAWING: Figure 3

    【課題】製造工程の簡単化及び機械的強度の十分な担保を実現できる鉄道車両用中心ピン、鉄道車両用台車、及び鉄道車両用中心ピンの製造方法を提供する。【解決手段】中心ピン10は、鉄道車両の車体Aと車体Aの下方に配置される台車枠2とを連結する中心ピン10であって、筒状の本体部30と、本体部30の下端部30cにおいて本体部30の外側面30eよりも張り出すフランジ部31と、本体部30の外側面30eに対して結合され、本体部30の変位を規制するストッパ18を受けるストッパ受け部32と、本体部30の外側面30eに対して結合され、本体部30の振動を緩和するダンパ19を受けるダンパ受け部33と、を備え、本体部30及びフランジ部31は、一体の鍛造体であり、ストッパ受け部32及びダンパ受け部33は、いずれも鍛造体であり、ストッパ受け部32は、本体部30の外側面30eに対して溶接されている。【選択図】図3
