To prevent, in a vehicle door opening/closing device, direct transmission of vibration during vehicle running to a reduction mechanism.SOLUTION: The vehicle door opening/closing device includes: a motor 31; first reduction mechanisms that reduce the rotation of the motor 31; an output shaft 39 that can rotate integrally with an output gear 37 of the first reduction mechanisms 36, 37; an upper casing 34 that supports the motor 31 and the first reduction mechanisms 36, 37; a second reduction mechanism 22 that is connected to the output shaft 39 and is linked to a door via a movable connecting member 12; and a lower casing 21 that is fixed to a vehicle body and rotatably supports the second reduction mechanism 22. The upper casing 34 is fastened and fixed to the lower casing 21 by fastening members 321, 331 via elastic seismic isolation members 32, 33 so as not to be in direct contact with the lower casing 21.SELECTED DRAWING: Figure 7 【課題】車両用ドア開閉装置において、車両走行時における振動が減速機構に直接伝達されないようにする。【解決手段】モータ３１と、モータ３１の回転を減速する第１減速機構と、第１減速機構３６、３７の出力ギヤ３７と一体的に回転可能な出力軸３９と、モータ３１及び第１減速機構３６、３７を支持するアッパーケーシング３４と、出力軸３９に連結されると共に、可動連結部材１２を介してドアに連係される第２減速機構２２と、車体に固定されると共に、第２減速機構２２を回転可能に支持するロアケーシング２１と、を備える。アッパーケーシング３４は、ロアケーシング２１に対して直接接触しないように、弾性免震部材３２、３３を介してロアケーシング２１に締結部材３２１、３３１により締結固定される。【選択図】図７
