The overall thickness of the structure can be further reduced while a high reduction ratio is achieved. The speed reduction device is provided with a motor and a speed reduction component, the motor and the speed reduction component are arranged in the axial direction, and the speed reduction component is provided with a first gear arranged on the side, away from the motor, of a first motor shell, a second gear meshed with the first gear and a third gear meshed with the second gear. The first gear, the second gear and the third gear are located on one side of the first motor shell in the axial direction, the speed reduction component is provided with at least one bearing arranged on the inner side of the first gear in the radial direction, the number of the first gear is at least one, and the second gear and the third gear respectively comprise two gears arranged adjacent to each other in the axial direction. The thickness of the whole structure in the axial direction and the radial direction can be further r
