  • Patent number: 10658645
    Abstract: A busbar module includes a busbar holding plate and a busbar cover attached to the busbar holding plate. The busbar holding plate includes a busbar holding face and a bearing including a hole and a wall to define the hole. The busbar cover includes protrusions protruding toward each other in the axial direction at positions corresponding to the hole. The protrusions are opposed to each other with a gap less than a dimension of the hole in the axial direction. The protrusions are disposed in the hole to rotate the busbar cover about the protrusions between a covering position and an uncovering position. The busbar cover is flexible to deform such that the gap expands to allow the wall to pass through the gap during attachment of the bulbar cover to the busbar holding plate and restores its original shape when passing of the wall through the gap is complete.
