PROBLEM TO BE SOLVED: To provide a battery pack for driving an electric vehicle which enables easy assembly of a lower case 11 and an upper case 12 of a battery pack 1 and accurate positioning relative to a vehicle body.SOLUTION: A battery pack 1 for an electric vehicle is attached to a lower surface of a vehicle body floor from the lower side and a bottom part of the battery pack protrudes to the lower side from a vehicle body floor. A lower case 11 forming a case 10 is formed along with an upper case 12 by die-casting an aluminium alloy and includes a pair of locator pins 31, 32 having tapered tip parts. The locator pins 31, 32 fit in locator holes 121, 122 of the upper case 12 and further fit in locator holes at the vehicle body side.SELECTED DRAWING: Figure 4
【課題】バッテリパック1のロアケース11とアッパケース12との組立を容易にするとともに、車体に対する正確な位置決めを行う。【解決手段】電気自動車用のバッテリパック1は、車体フロアの下面に下側から取り付けられており、底部が車体フロアから下方に突出している。ケース10を構成するロアケース11は、アッパケース12とともにアルミニウム合金のダイキャストからなり、テーパ状の先端部を有する一対のロケートピン31,32を有する。ロケートピン31,32はアッパケース12のロケート孔121,122に嵌合し、さらに車体側のロケート孔に嵌合する。【選択図】図4
