To provide a power-assisted transport cart characterized in that an assist force exerted by a motor can be applied by either pushing or pulling the cart and the motor will not obstruct traveling after discharge of a battery.SOLUTION: A power-assisted transport cart 1 includes drive wheels 11 and 16 attached to the transport cart, motors 15A and 15B that drive the respective drive wheels, a handlebar 4 for use in pulling the transport cart, a battery that feeds electric power to the motors, and a control unit that rotates and controls the motors. The power-assisted transport cart includes torque transmission mechanisms 60A and 60B that transmit drive forces of the respective motors 15A and 15B but do not transmit torques, which are conveyed from the respective drive wheels, to the motors. A load sensor having plural strain gauges exists in the middle of the handlebar 4. The control unit uses an output of the load sensor to drive the right motor 15A and left motor 15B.SELECTED DRAWING: Figure 2

    【課題】押しても引いてもモータによるアシスト力を印加でき、バッテリの放電後にはモータが走行の障害にならないようにした電動アシスト運搬車を提供する。【解決手段】運搬車に設けられる駆動輪11、16と、これらを駆動するモータ15A、15Bと、運搬車を引くためのハンドル部4と、モータに電力を供給するバッテリと、モータの回転制御をする制御部を有する電動アシスト運搬車1において、モータ15A、15Bの駆動力を伝達すると共に駆動輪からの回転力をモータに伝達しないトルク伝達機構部60A、60Bを設けた。ハンドル部4の途中には複数のひずみゲージを有する荷重センサ部が介在され、制御部は荷重センサ部からの出力を用いて右モータ15A及び左モータ15Bを駆動する。【選択図】図2
