To reduce displacement allowance required for a joint unit while suppressing increase in unspring weight in a wagon in a structure having a motor directly connected to an axle through a joint.SOLUTION: A wagon includes: a wagon frame; an axle including a non-rotational unit for supporting the wagon frame through an axle spring; a drive unit including a hollow motor into which the axle is inserted and a motor bracket which retains the motor and is supported by the wagon frame in a state of being capable of moving relatively upward; a joint unit coupling the motor and the axle in a power transmittable manner; and a guide unit provided in the non-rotational unit for restricting displacement of the drive unit from the axle by abutting to the drive unit when the wagon frame is displaced from the axle by a prescribed amount or more.SELECTED DRAWING: Figure 1

    【課題】モータが継手を介して車軸に直接接続される構造の台車におけるばね下重量の増大を抑制しつつ、継手部に要求される変位許容量を小さくする。【解決手段】台車フレームと、軸ばねを介して台車フレームを支持する非回転部を含む、車軸と、車軸が挿通された中空形状のモータと、モータを保持し、上方向に相対移動可能な状態で台車フレームに支持されたモータブラケットと、を含む、駆動部と、モータと車軸とを、動力伝達可能に連結する継手部と、非回転部に設けられ、台車フレームが車軸に対して所定量以上変位した場合に駆動部と当接して、駆動部の車軸に対する変位を規制するガイド部と、を備える。【選択図】図1
