<p>PROBLEM TO BE SOLVED: To provide a battery pack that can suppress breaking of a fixing bracket for fixing a battery body to a member to be fixed.SOLUTION: End plates 31, 32 are provided at both the ends in the juxtaposition direction of a battery cell 24 in a battery body 22. Brackets 41, 51 are fixed to the end plates 31, 32. A bolt B2 for fastening the second bracket 51 to a side wall 13a fastens the second bracket 51 with fastening force which suppresses sliding of the second bracket 51 even when a stationary load corresponding to the sum of a load applied to the second bracket 51 due to expansion of the battery cell 24 under charging and a load applied to the second bracket 51 due to vibration of the battery pack is applied from the battery body 22 side. Furthermore, the bolt B2 for fastening the second bracket 51 fastens the second bracket 51 with fastening force which allows sliding of the second bracket 51 when a load which is larger than the stationary load and smaller than a breaking load with which the bracket 51 is broken is applied from the battery body 22 side.</p> |
