PROBLEM TO BE SOLVED: To provide a window drive apparatus with a high reduction gear ratio.SOLUTION: A window drive apparatus includes an electric motor and a gear train. The gear train includes a first deceleration mechanism and a second deceleration mechanism. The first deceleration mechanism includes a worm driven by the electric motor and a worm gear meshed with the worm. The second deceleration mechanism includes a first driving gear and a second driving gear coaxially fixed and respectively located at opposite sides of the worm gear, a first driven gear meshed with the first driving gear and a second driven gear meshed with the second driving gear. The first driven gear and the second driven gear are coaxially fixed together. A vehicle door including the window drive apparatus is also provided.SELECTED DRAWING: Figure 5 【課題】減速比が大きいウインドウ駆動装置を提供する。【解決手段】ウインドウ駆動装置は、電気モータ及び歯車列を含む。歯車列は、第１の減速機構及び第２の減速機構を含む。第１の減速機構は、電気モータによって駆動されるウォームと、ウォームと噛み合ったウォームギヤーとを含む。第２の減速機構は、同軸に固定されてそれぞれウォームギヤーの反対側面に位置する第１の駆動歯車及び第２の駆動歯車と、第１の駆動歯車と噛み合った第１の被動歯車と、第２の駆動歯車と噛み合った第２の被動歯車とを含む。第１の被動歯車及び第２の被動歯車は、一緒に同軸に固定される。ウインドウ駆動装置を含む車両ドアも提供される。【選択図】図５
