To provide a drive device that can be downsized, and a movable body using the drive device.SOLUTION: A drive device has a motor portion 20 that has a motor shaft 21, and a speed reduction mechanism 30 connected to the motor shaft. The speed reduction mechanism has a sun gear portion 31 disposed on the motor shaft, a planetary gear portion 32 that engages with the sun gear portion and is aligned in a circumferential direction, a carrier 34 that at least partially surrounds the planetary gear portion, and an output portion 35 connected to the planetary gear portion. The carrier has a first cylinder portion 341 that is disposed outside and above the sun gear portion and extends in an axial direction. The first cylinder portion rotatably supports an output portion via a bearing Br, and at least a part of the bearing is disposed on the inner side in a diametrical direction of an outer end in the diametrical direction of the planetary gear portion.SELECTED DRAWING: Figure 4
【課題】小型化できる駆動装置及び駆動装置を用いた移動体を提供する。【解決手段】モータシャフト21を有するモータ部20と、モータシャフトに接続する減速機構30とを有する。減速機構は、モータシャフトに配置される太陽歯車部31と、太陽歯車部と噛み合うとともに、周方向に配列される遊星歯車部32と、少なくとも一部が遊星歯車部を囲むキャリア34と、遊星歯車部と接続される出力部35と、を有する。キャリアは、太陽歯車部の外方かつ上方に配置され、軸方向に延びる第1筒部341を有する。第1筒部は、軸受Brを介して出力部を回転可能に支持し、軸受の少なくとも一部は遊星歯車部の径方向外端よりも径方向内方に配置される。【選択図】図4
