<p>PURPOSE: A battery module is provided to improve impact resistance and vibration resistance by accepting a vibration absorption structure in a battery case of double structure, and improving assembling and repair workability. CONSTITUTION: A battery module(100) comprises a plurality of unit battery packs(140), an inner case(110) providing a unit battery packs-accepting space, an outer case(120) accepting the inner case, and an elastic buffer part(130) inserted between the inner case and the outer case. The elastic buffer part elastically supports the inner case from the outer case. In front of the outer case, a cooling fan module(150) for deriving air flow to front and rear directions of the outer case is mounted.
