To provide a vehicle back door opening-closing device that suppresses the generation of operating noise in a one-sided vehicle back door opening-closing device.SOLUTION: A vehicle back door opening-closing device 1 includes a drive-side actuator that is installed on one side in the width direction of the vehicle and is driven by a motor to expand and contract to open and close the back door, and a non-drive side actuator 4 provided on the other side in the width direction of the vehicle and expands and contracts according to the opening-closing operation of the back door. The non-drive side actuator 4 comprises a housing 41, a driven portion 43 that appears and disappears with respect to the housing 41 following an opening-closing operation, and a sliding resistance generating portion 44 (non-driving side sliding resistance generating portion) provided between the housing 41 and the driven portion 43. The magnitude of the sliding resistance generated by the sliding resistance generating portion 44 is larger than the sliding resistance generated by the driving side actuator due to the expansion and contraction operation of the driving side actuator.SELECTED DRAWING: Figure 3

    【課題】片側駆動の車両バックドア開閉用装置において、作動音の発生を抑制した車両バックドア開閉用装置を提供する。【解決手段】車両バックドア開閉用装置1は、車両の幅方向の一方に設けられ、モータにより伸縮駆動してバックドアの開閉動作を行う駆動側アクチュエータと、車両の幅方向の他方に設けられ、バックドアの開閉動作に追従して伸縮する非駆動側アクチュエータ4と、を備える。非駆動側アクチュエータ4は、ハウジング41と、開閉動作に追従してハウジング41に対して出没する従動部43と、ハウジング41と従動部43との間に設けられる摺動抵抗発生部44(非駆動側摺動抵抗発生部)と、を備え、摺動抵抗発生部44により生じる摺動抵抗の大きさは、駆動側アクチュエータの伸縮動作に伴い駆動側アクチュエータで生じる摺動抵抗よりも大きい。【選択図】図3
