PROBLEM TO BE SOLVED: To provide a truck device of which meandering stability and curve passage performance can be improved.SOLUTION: A truck device 110 of a railway vehicle 10 comprises a truck frame 130 which so mounted as to be bridged over two vehicle bodies 100 which are linked to each other via an inter-vehicle linkage bar device 120, three sets of wheel shafts 140, 150 which are provided on the truck frame 130 along a travel direction of the vehicle body 100, and a steering frame 160 which is rotated around a lateral direction center position of cross beams 131 in the front and rear of the truck frame 130. The wheel shaft 140, which is provided at both of front and rear ends of the truck frame 130, is a power wheel shaft to which power for rotating the wheel shaft 140 is transmitted, and is connected to and is rotated integrally with the steering frame 160. The wheel shaft 150, which is provided at a center of the truck frame 130, is a powerless wheel shaft to which power for rotating the wheel shaft 150 is not transmitted, and regulated in rotation, and becomes an original point of steering of the power wheel shaft.SELECTED DRAWING: Figure 2

    【課題】蛇行動安定性と曲線通過性能を向上させることの可能な台車装置を提供する。【解決手段】鉄道車両10の台車装置110であって、車体間連接棒装置120を介して連接された2つの車体100にまたがって取り付けられる台車枠130と、台車枠130に車体100の進行方向に沿って設けられる3組の輪軸140、150と、台車枠130の前後の横ばり131の横方向中央位置を中心に旋回する操舵フレーム160と、を備え、台車枠130の前後両端に設けられる輪軸140は、輪軸140を回転させる動力が伝達される動力輪軸であり、かつ操舵フレーム160に連結されて一体に旋回し、台車枠130の中央に設けられる輪軸150は、輪軸150を回転させる動力が伝達されない無動力輪軸であり、かつ旋回が規制されて動力輪軸の操舵の起点となることを特徴とする。【選択図】図2
