A drive device is provided with: a motor unit having a motor shaft; and the speed reducing mechanism is connected with the motor shaft. The speed reduction mechanism includes: a sun gear portion disposed on the motor shaft; planetary gear parts which mesh with the sun gear part and are arranged in the circumferential direction; a planet carrier at least partially surrounding the planet gear portion; and an output portion connected with the planetary gear portion. The planet carrier is provided with a first cylinder part which is arranged on the outer side and the upper side of the sun gear part and extends in the axial direction. The first cylinder portion rotatably supports the output portion via a bearing, and at least a portion of the bearing is disposed radially inward of a radially outer end of the planetary gear portion.
一种驱动装置,具有:具有马达轴的马达部;以及与马达轴连接的减速机构。减速机构具有:配置在马达轴上的恒星齿轮部;与恒星齿轮部啮合并且沿周向排列的行星齿轮部;至少一部分包围行星齿轮部的行星架;以及与行星齿轮部连接的输出部。行星架具有第一筒部,其配置在恒星齿轮部的外侧且上方,且沿轴向延伸。第一筒部经由轴承可旋转地支撑输出部,轴承的至少一部分配置在比行星齿轮部的径向外端靠径向内侧的位置。
