To reduce costs of an elastic bush device of a traction device of a railway vehicle.SOLUTION: An elastic bush device of a traction device comprises: an outer cylinder supported to a truck; an inner cylinder into which a central pin is fitted, and which is arranged with a distance to a radially inward side of the outer cylinder, and arranged so as to deviate upward from the outer cylinder; and an elastic body held between the inner cylinder and the outer cylinder. An outer peripheral surface of the inner cylinder opposite to the elastic body is inclined downward, an inner peripheral surface of the outer cylinder opposite to the elastic body is inclined upward, and the elastic body has such a shape that an inner cylinder-side surface deviates upward from an outer cylinder-side surface.SELECTED DRAWING: Figure 6
【課題】鉄道車両の牽引装置の弾性ブッシュ装置のコストダウンを図る。【解決手段】牽引装置の弾性ブッシュ装置は、台車に支持される外筒と、前記中心ピンが嵌入され、前記外筒の径方向内側に距離をとって配置され、前記外筒に対して上側にずれて配置された内筒と、前記内筒と前記外筒との間に挟まれた弾性体と、を備える。前記内筒の前記弾性体に対向する外周面は下方に向けて傾斜し、かつ、前記外筒の前記弾性体に対向する内周面は上方に向けて傾斜し、前記弾性体は、前記内筒側の面が前記外筒側の面に対して上側にずれた形状を有する。【選択図】図6
