To provide an assist unit for a bogie which can be attached to an existing bogie, alleviates a force necessary for an initial motion, and can perform an assist in a long distance longer than a conventional assist mechanism, and a bogie with an assist having the assist unit for the bogie.SOLUTION: An assist unit for a bogie has: drive wheels 102; a spring 105b for generating torque for rotating the drive wheels; an output shaft 105c for transmitting the torque to the drive wheels from the spring; a charge mechanism for rotating the output shaft by an operation of a user, and winding and fastening the spring; a drive wheel holding mechanism for holding the drive wheels, and switching a position in which the drive wheels contact with the ground surface or a floor surface, and a position in which the drive wheels do not contact with the ground surface or the floor surface; a power assist mechanism having a rotation control mechanism for switching a first state for permitting the rotation of the output shaft in only a direction in which the spring is wound and fastened, and a second state for permitting the free rotation of the output shaft; and an attachment mechanism for attaching the power assist mechanism to a bogie 200.SELECTED DRAWING: Figure 6

    【課題】既存の台車に取り付けることが可能であり、初動に必要な力を軽減し、従来のアシスト機構よりも長い距離のアシストが可能な台車用アシストユニット、及び、当該台車用アシストユニットを備えたアシスト付き台車を提供する。【解決手段】駆動輪102と、駆動輪を回転させるトルクを発生させるゼンマイ105bと、ゼンマイから駆動輪にトルクを伝達する出力軸105cと、使用者の操作により出力軸を回転させ、ゼンマイを巻き締めるチャージ機構と、駆動輪を保持し、駆動輪が地面又は床面に接触する位置と、地面又は床面に非接触の位置とを切り替える駆動輪保持機構と、ゼンマイを巻き締める方向にのみ出力軸の回転を許す第1の状態と、出力軸の自由な回転を許す第2の状態とを切り替える回転制御機構を備えるパワーアシスト機構と、パワーアシスト機構を台車200に取り付ける取付機構とを有するものとする。【選択図】 図6
