To prevent vibration of a door upon opening the door.SOLUTION: A door opening/closing device includes: an actuator 5 having a drive source 10, an output shaft section 11 that can rotate forward and reversely, and a reduction mechanism 12 that reduces a driving force of the drive source 10 by multiple gears 13, 14 to transmit the force to the output shaft section 11; a case 6 that houses at least the drive source 10 and is fixed to a door installed on a vehicle body in an opening/closing manner; a lever 7 that is fixed to the output shaft section 11 and rotates forward to operate the door in the opening direction while rotating reversely to operate the door in the closing direction; a link 8 that connects the lever 7 to the vehicle body; and an urging member 9 that urges the door in either one of the opening direction or the closing direction.SELECTED DRAWING: Figure 1 【課題】開放時にドアに振動が発生することを防止する。【解決手段】ドア開閉装置は、駆動源１０、正逆回転可能な出力軸部１１、及び駆動源１０の駆動力を複数の歯車１３，１４により減速して出力軸部１１に伝達する減速機構１２を有するアクチュエータ５と、少なくとも駆動源１０が収容され、車体に開閉可能に取り付けたドアに固定されるケース６と、出力軸部１１に固定され、正回転してドアを開方向に動作させる一方、逆回転してドアを閉方向に動作させるレバー７と、レバー７と車体とを連結するリンク８と、ドアを開方向または閉方向のいずれか一方に付勢する付勢部材９とを備える。【選択図】図１
