The present invention provides a battery pack, which includes a plurality of battery modules where a plurality of battery cells are provided within a module case, comprising: an upper case (110) formed with a chamfer (111) with predetermined length in the length direction of a side surface at a portion where an upper surface comes into contact with both side surfaces; a first battery module formed with a first chamber excessive push prevention unit (121) extended in a side and upward direction from the module case and a first module excessive push prevention unit (122) extended in a side direction from the module case; a second battery module formed with a second chamber excessive push prevention unit (131) extended in a side and upward direction from the module case and a second module excessive push prevention unit (132) extended in a side direction from the module case, and arranged to be adjacent to the first battery module; and a lower plate (140) formed with a plurality of module support units (141) fixating lower ends of the first battery module and the second battery module. The battery pack according to the present invention can be stably driven as the fixation unit and fixation members fill a space within the battery pack and have the battery modules to be firmly fixated to the battery pack case.
