Zusammenfassung:To prevent a lubricant from leaking outside a gear cover from a facing part.SOLUTION: A motor of a drive device includes: a shaft extending in an axial direction along a center axis; and a drive gear rotatable together with the shaft about the center axis. A gear part for transmitting torque of the motor to an output part includes: a first gear that engages with the drive gear; and a gear cover 60 surrounding at least parts of the drive gear and first gear as viewed from the axial direction. A first gear cover 61 and a second gear cover 62 of the gear cover are disposed to face each other in the axial direction. A facing part at which the other-end part of the first gear cover in the axial direction and a one-end part of the second gear cover in the axial direction face each other in the axial direction includes a first facing part that faces a first engaging part of the first gear and the drive gear in a direction perpendicular to the axial direction with a gap therebetween.SELECTED DRAWING: Figure 11A 【課題】本発明は、潤滑材が対向部からギヤカバーの外部に漏れることを抑制する。【解決手段】駆動装置のモータは、中心軸に沿って軸方向に延びるシャフトと、中心軸を中心にしてシャフトとともに回転可能な駆動歯車と、を有する。モータのトルクを出力部に伝達するギヤ部は、駆動歯車と噛み合う第1歯車と、軸方向から見て駆動歯車及び第1歯車の少なくとも一部を囲むギヤカバー60と、を有する。ギヤカバーの第1ギヤカバー61及び第2ギヤカバー62は、互いに軸方向に対向して配置される。第1ギヤカバーの軸方向他方端部と第2ギヤカバーの軸方向一方端部とが軸方向に対向する対向部は、第1歯車及び駆動歯車の第1噛合部分と隙間を空けて軸方向と垂直な方向に対向する第1対向部を有する。【選択図】図11A
