Document Type and Number:
Japanese Patent JP2020143776
Kind Code:
A
Abstract:
To achieve downsizing in an axial direction.SOLUTION: A power transmission device 1 has: a motor 2; a planetary reduction gear 5 connected to the downstream of the motor 2; and a differential gear 6 connected to the downstream of the planetary reduction gear 5. The motor 2, the planetary reduction gear 5, and the differential gear 6 overlap in a rotation axis X direction. When viewed in the rotation axis X direction of the motor 2, the planetary reduction gear 5 and the differential gear 6 are provided so as to fit in a height range of the motor 2. In the rotation axis X direction of the motor 2, the motor 2 is located between the planetary reduction gear 5 and the differential gear 6.SELECTED DRAWING: Figure 1
