PROBLEM TO BE SOLVED: To suppress generation of vibration by enhancing the rigidity of a plate member (42) and improving the fitting rigidity.SOLUTION: A battery pack (1) for an electric automobile has a pair of stacks (20) fixed in a pack case (10). The stack (20) includes a plurality of battery modules (21). A channel member (41) is fixed on each lateral face of the pair of stacks (20). The plate member (42) is fixed on the pair of channel members (41). A bent part (56) bent in a vertical direction (α3) is formed to the plate member (42). A protruded or depressed bead part (60) is formed to the bent part (56) to improve the rigidity. |
