PROBLEM TO BE SOLVED: To prevent amplification of vibration in a battery module which comprises battery cells and frame members stacked onto each other.SOLUTION: In a battery module 10, battery cells 12 and frame members 14 are alternatively stacked on each other. In front surfaces 14a facing the battery cells 12 in the frame members 14, a plurality of ribs 16 (protruded members) linearly extend in a width direction (Y direction) at intervals. Between the ribs 16, passages are formed through which cooling air flows. The ribs 16 are elastic members such as rubbers and sponges, and adhered against the battery cells 12 with adhesive.SELECTED DRAWING: Figure 2 |
