To provide a housing structure of a motor for an electric vehicle capable of suppressing a short circuit due to breakage of a component having an inlay structure when a load in the shear direction is applied between two housings.SOLUTION: A housing structure of a motor for an electric vehicle includes a housing that includes a first housing and a second housing attached to the first housing, and the motor is housed in the housing. The first housing has an in-row protrusion protruding from the first surface on the inner peripheral side of a first surface facing the second housing, and the second housing has a recess that meshes with an in-row protrusion on the second surface in contact with the first surface. On the first surface, a groove having a curved cross section in the radial direction and connected to the side surface of the in-row protrusion is formed along the outer peripheral side of the in-row protrusion.SELECTED DRAWING: Figure 5
【課題】2つのハウジング間にせん断方向の荷重がかかるときに、インロー構造の部品の折損によるショートを抑制できる電動車両用モータの筐体構造を提供する。【解決手段】電動車両用モータの筐体構造は、第1ハウジングと、第1ハウジングに取り付けられる第2ハウジングとを含む筐体を備え、筐体内にモータが収容される。第1ハウジングは、第2ハウジングに臨む第1の面の内周側に第1の面から突出するインロー突起を有し、第2ハウジングは、第1の面と当接する第2の面にインロー突起とかみ合う凹部を有する。第1の面には、径方向の断面が曲面状をなしてインロー突起の側面と繋がる溝がインロー突起の外周側に沿って形成される。【選択図】図5
