An electric power unit (1) in which at least an electric motor (10) is housed in a case (2) is characterized in that polygonal rib regions (S1, S2) in which polygonal ribs (8) are formed are provided on at least two surfaces of the outer peripheral surface of the case (2), and the polygonal rib regions (S1, S2) are connected to each other by circumferential ribs (9). Here, a first axial rib (6) and a second axial rib (7), which extend parallel to the axial direction, are formed on the outer peripheral surface of the housing (2), and the polygonal rib regions (S1, S2) are provided in a portion sandwiched between the first axial rib (6) and the second axial rib (7). In addition, the circumferential ribs (9) are formed throughout the entire circumferential direction of the polygonal rib regions (R1, R2). In addition, the polygonal ribs (8) are honeycomb ribs.

    一种壳体(2)内至少收纳电动马达(10)的电动动力单元(1),其特征在于,在所述壳体(2)的外周面的至少两个面上设置形成有多边形肋(8)的多边形肋区域(S1、S2),并通过周向肋(9)将所述多边形肋区域(S1、S2)彼此连接。在此,在上述壳体(2)的外周面形成有与轴向平行地延伸的第一轴向肋(6)和第二轴向肋(7),上述多边形肋区域(S1、S2)设置在由上述第一轴向肋(6)和上述第二轴向肋(7)夹着的部分。另外,上述周向肋(9)遍及上述多边形肋区域(R1、R2)的周向整体而形成。另外,多边形肋(8)是蜂窝肋。
