<P>PROBLEM TO BE SOLVED: To provide a battery module preventing easy detachment of a case. <P>SOLUTION: In a battery module M, a battery cell 2 is stored within a case 1 formed by superposing peripheral edge parts 11a, 12a of a pair of cases 11, 12 on each other. Engagement holes 13 penetrating in a plate thickness direction of a wall face are installed on the peripheral edge part 11a of the one case 11, and projections 14 formed by cut and rise in a plate thickness direction of a wall face are installed in positions of the peripheral edge part 12a of the other case 12, corresponding to the engagement holes 13. When the one case and the other case are elastically energized in the directions separating from each other via the battery cell 2, the engagement holes 13 and the projections 14 abut on each other, so as to fix the positions of the one case and the other case. <P>COPYRIGHT: (C)2012,JPO&INPIT |
