Abstract: A cover body has: a plurality of divided cover portions arranged side by side in a Y axis direction; an elastic deformation portion extending between the divided cover portions adjacent to each other; a first connection portion provided in a first divided cover portion disposed at one end portion in the Y axis direction, the first connection portion being connected to the attachment-target member so as to be fixed in the Y axis direction; a second connection portion provided in a second divided cover portion disposed at the other end portion in the Y axis direction, the second connection portion being connected to the attachment-target member so as to be fixed in the Y axis direction; and a third connection portion disposed between the first connection portion and the second connection portion and connected to the attachment-target member so as to be slidable in the Y axis direction.

Abstract: A battery module includes: a plurality of stacked battery cells; a first cover body and a second cover body provided to cover the plurality of battery cells in a direction orthogonal to a stacking direction of the battery cells; a pair of binding bars that restrain the plurality of battery cells in the stacking direction of the battery cells; and a retainer connected to each of the binding bars. The first cover body has a first overlapping portion. The second cover body has a second overlapping portion disposed between each of the battery cells and the first overlapping portion and overlapping with the first overlapping portion in a direction orthogonal to the stacking direction of the battery cells. The first cover body is disposed between each of the battery cells and the retainer in the direction orthogonal to the stacking direction of the battery cells.

Abstract: A battery module includes: a stack including a plurality of battery cells arranged side by side in a first direction. A reference plane for positioning the stack in a direction orthogonal to the first direction is provided. The cover member includes a biasing portion that biases the stack in a direction away from the cover member. The biasing portion biases the stack to press the stack against the reference plane.

Abstract: A battery module includes: a stack including a plurality of battery cells arranged side by side in a first direction; and a cover member having an insulating property, the cover member being provided to cover the stack from a side opposite to the electrode terminal. The cover member includes a first drainage portion located at a center portion of the cover member in a second direction orthogonal to the first direction, and a second drainage portion located at each of both end portions of the cover member in the second direction.
