PROBLEM TO BE SOLVED: To make it possible to exhibit an assist effect in only a period in which such an assist effect is required during transport travelling of a carriage.SOLUTION: A power-assisted carriage has: a vehicle body having a load-carrying platform; an in-wheel motor attached to the vehicle body; a wheel with a motor to which the in-wheel motor is attached; a controller; and a torque sensor which detects a torque acting on a predetermined part of a handle attached to the vehicle body when the handle is pushed by a user. In the power-assisted carriage, the controller operates the in-wheel motor when the torque sensor detects a torque equal to or more than a pre-set threshold, and stops the in-wheel motor at a point of time when a pre-set time has lapsed after the torque sensor detected a torque equal to or more than the pre-set threshold.SELECTED DRAWING: Figure 10

    【課題】台車の運搬走行中、アシスト効果を必要とする期間に限ってアシスト効果を発揮させる。【解決手段】荷台を有する車体と、車体に取り付けられたインホイールモータと、インホイールモータが取り付けられたモータ付き車輪と、コントローラと、車体に取り付けられたハンドルがユーザによって押されている際にハンドルの所定部分に作用するトルクを検知するトルクセンサと、を有する電動アシスト台車において、コントローラは、トルクセンサが予め設定された閾値以上のトルクを検知したときにインホイールモータを作動させ、トルクセンサが閾値以上のトルクを検知してから予め設定された時間が経過した時点でインホイールモータを停止させる。【選択図】図10
