PROBLEM TO BE SOLVED: To provide a power-assisted carry cart that can easily change the travelling direction during travelling.SOLUTION: A power-assisted carry cart includes a main body, a drive shaft, a clutch unit provided between at least one of wheels and the drive shaft, a drive unit configured to transmit a driving force to the drive shaft. The clutch unit is connected so as to receive the driving force of the drive shaft and is coupled so that a cylindrical housing of the clutch unit can synchronously rotate with the wheels. At least one of the wheels, which is connected to the cylindrical housing is configured to receive the driving force of the drive shaft and allow movement of the main body. The clutch unit is configured so that when the rotation speed of at least one of the wheels is higher than the rotation speed of the drive shaft, the driving force from the drive shaft is not transmitted to one of the wheels.SELECTED DRAWING: Figure 3(a)
【課題】移動中の方向変換が容易に行える電動アシストキャリーカートを提供する【解決手段】本体部と、駆動軸と、車輪の少なくとも一方と駆動軸との間に設けられるクラッチ・ユニットと、駆動軸に駆動力を伝達する駆動部と、を備え、クラッチ・ユニットが駆動軸の駆動力を受けるように接続されると共に、クラッチ・ユニットの円筒状ハウジングと車輪とが同期回転可能なように結合され、円筒状ハウジングに接続された少なくとも一方の車輪は、駆動軸の駆動力を受けて本体部の移動を許容するように構成され、少なくとも一方の車輪の回転速度が駆動軸の回転速度より早い場合に、駆動軸からの駆動力が一方の車輪に伝達されないようにクラッチ・ユニットが構成される、電動アシストキャリーカート。【選択図】図3(a)
