PROBLEM TO BE SOLVED: To provide a truck device for a railway vehicle capable of suppressing induction of forced oscillation of a vehicle body.SOLUTION: A truck device 100 for a railway vehicle comprises: a truck frame 110 which is attached to a vehicle body frame 10; two sets of wheel shafts 120-1 and 120-2 arranged on the truck frame 110 in an advance direction of the vehicle body; and motors 200 each of which is disposed on an axle 122 of the wheel shaft 120, and rotatably drives the wheel shaft 120. The motor 220 includes: a stator 220 in which a shaft center of the axle 122 is inserted rotatably, and fixed to the truck frame 110; and rotors 240 which are arranged so as to rotate relatively, at both end parts of the stator 220 in an axial direction of the axle 122, with a magnetic space J, and rotate integrally with the axle 122 inserting the shaft center. Delivery and reception of electromagnetism from the stator 220 to the rotors 240 are performed in axial directions of the axles 122.SELECTED DRAWING: Figure 3

    【課題】車体の強制振動の誘発を抑えることの可能な鉄道車両の台車装置を提供する。【解決手段】鉄道車両の台車装置100は、車体フレーム10に取り付けられる台車枠110と、台車枠110に車体の進行方向に沿って設けられる2組の輪軸120−1、120−2と、輪軸120の車軸122に設けられ、輪軸120を回転駆動するモータ200と、を備え、モータ220は、車軸122が軸心を回転自在に挿通し、台車枠110に固定される固定子220と、車軸122の軸方向において固定子220の両端部に磁気空間Jを構成して相対回転可能に配置され、軸心を挿通する車軸122と一体回転する回転子240と、を備え、固定子220から回転子240への電磁気の受け渡しが車軸122の軸方向間で行われることを特徴とする。【選択図】図3
