To provide a drive unit for a man power drive vehicle which enables reduction of loss of man power drive force.SOLUTION: A drive unit for a man power drive vehicle includes: an electric motor which assists propulsion of a man power drive vehicle; a crank shaft; an output part which is coupled to the crank shaft, turns in a first rotation direction when the crank shaft rotates in the first rotation direction, and turns in a second rotation direction when the crank shaft rotates in the second rotation direction; a speed reduction mechanism which reduces a rotation speed of the electric motor at multiple stages; and a clutch mechanism which is provided between the output part and the speed reduction mechanism and transmits rotational force of the electric motor from the speed reduction mechanism to the output part.SELECTED DRAWING: Figure 4 【課題】人力駆動力の損失を低減できる人力駆動車用ドライブユニットを提供する。【解決手段】人力駆動車用ドライブユニットは、人力駆動車の推進をアシストする電気モータと、クランク軸と、前記クランク軸に連結され、第１回転方向に前記クランク軸が回転する場合、前記第１回転方向に回転し、前記第２回転方向に前記クランク軸が回転する場合、前記第２回転方向に回転する出力部と、前記電気モータの回転速度を複数段階で減速する減速機構と、前記出力部と前記減速機構との間に設けられ、前記減速機構から前記出力部に前記電気モータの回転力を伝達するクラッチ機構と、を含む、【選択図】図４
