Abstract
Official abstract text for this publication.
In an electric power unit which accommodates at least an electric motor in a housing, polygonal rib regions in which polygonal ribs are respectively formed are provided on at least two surfaces of an outer peripheral surface of the housing, and the polygonal rib regions are connected by a circumferential rib. Here, a first axial rib and a second axial rib extending parallel to an axial direction are formed on the outer peripheral surface of the housing, and the polygonal rib region is provided in a portion sandwiched between the first axial rib and the second axial rib. Further, the circumferential rib is formed over the entire part of the polygonal rib region in a circumferential direction. Note that the polygonal rib is a honeycomb rib.
First claim
Opening claim text (preview).
What is claimed is: 1. An electric power unit that accommodates at least an electric motor in a housing, the electric power unit comprising: polygonal rib regions provided on at least two surfaces of an outer peripheral surface of the housing, the polygonal rib regions respectively including polygonal ribs; and a circumferential rib connecting the polygonal rib regions. 2. The electric power unit according to claim 1 , further comprising a first axial rib and a second axial rib extending parallel to an axial direction and formed on the outer peripheral surface of the housing, wherein the polygonal rib region is provided in a portion sandwiched between the first axial rib and the second axial rib. 3. The electric power unit according to claim 1 , wherein the circumferential rib is formed over an entire part of the polygonal rib region in a circumferential direction. 4. The electric power unit according to claim 1 , further comprising a boss integrally formed at a longitudinally intermediate portion of the circumferential rib. 5. The electric power unit according to claim 1 , wherein both axial ends of the first and second axial ribs are connected to flange portions formed at both axial ends of the housing. 6. The electric power unit according to claim 1 , wherein the circumferential rib passes through a center of the polygonal rib. 7. The electric power unit according to claim 1 , wherein the polygonal rib is a honeycomb rib.
