POWER ASSISTED DRIVE SYSTEM

PROBLEM TO BE SOLVED: To provide a power assisted drive system which suppresses damage to its wiring.SOLUTION: A power assisted drive system which assists with the driving of a vehicle comprises: a motor; wiring electrically connected to the motor; a reduction gear mechanism which reduces the power of the motor; an output shaft which transmits the motor power reduced by the reduction gear mechanism to the vehicle drive wheel; and a housing which houses the motor and reduction gear mechanism, and from which the output shaft protrudes to the outside. The housing has a drawing part in which the wiring is drawn to the outside of the housing. The height position from the ground where the drive wheel makes contact is located at a position where the axial center of the output shaft is lower than the center of the housing, while the axial center of the motor and the drawing part are higher than the center of the housing.SELECTED DRAWING: Figure 5 【課題】配線の損傷が抑制された電動アシスト駆動装置を提供することを課題とする。【解決手段】車両の走行をアシストする電動アシスト駆動装置であって、モータと、前記モータに電気的に接続された配線と、前記モータの動力を減速する減速ギヤ機構と、前記減速ギヤ機構により減速された前記モータの動力を前記車両の駆動輪に伝達する出力軸と、前記モータ及び減速ギヤ機構を収納し、前記出力軸が外部に突出したハウジングと、を備え、前記ハウジングは、前記配線が当該ハウジングの外部に引き出された引出部を有し、前記駆動輪が接する地面からの高さ位置は、前記出力軸の軸心の方が前記ハウジングの中心よりも低い位置にあり、前記モータの軸心及び引出部の方が前記ハウジングの中心よりも高い位置にある、電動アシスト駆動装置。【選択図】図５
