DRIVE DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/004435
Kind Code:
A1
Abstract:
A drive device according to an aspect of the present invention comprises: a motive power transmission unit coupled to a rotary electrical machine on one side in the axial direction of the rotary electrical machine; and a housing that houses the rotary electrical machine and the motive power transmission unit. The housing has a gear cover that is positioned on one side in the axial direction of the motive power transmission unit and that supports a shaft of the motive power transmission unit. The gear cover has a dome part that projects to one side in the axial direction and that has the center at a dome axis extending in the axial direction. The dome part has a top section through which the dome axis passes, and an inclination section that expands from the top section outward in the radial direction. The inclination section is inclined more to the other side in the axial direction as the distance from the top section outward in the radial direction becomes greater. An inclination angle with respect to a surface orthogonal to the dome axis becomes larger as the distance from the top section outward in the radial direction becomes greater.
