To improve protection performance of a battery pack upon side impact and furthermore to suppress increase of size and weight of a support bracket.SOLUTION: A support device 10 of a vehicular battery pack 30 arranged between side rails 41 constituting a ladder frame 40 of a vehicle includes a frame side connection portion 1, a protrusion portion 2 and an elastic connection portion 6. The frame side connection portion 1 comes in contact with an end surface 41d on the outside in a vehicle width direction, of a web 41a of the side rail 41 and a lower surface 41e of a flange 41c extending to the inside in the vehicle width direction from the lower end of the web 41a. The protrusion portion 2 is provided in such a manner that it extends to the lower side in a vehicle height direction from a frame side connection portion 1 and protrudes to the outside in the vehicle width direction. The elastic connection portion 6 is connected to the protrusion portion 2 and suspends the battery pack 30 to the ladder frame 40.SELECTED DRAWING: Figure 5

    【課題】側突時のバッテリパックの保護性能を高めつつ、支持ブラケットの大型化及び高重量化を抑制する。【解決手段】車両のラダーフレーム40を構成するサイドレール41間に配置される車両用バッテリパック30の支持装置10は、フレーム側接続部1と突出部2と弾性連結部6とを含む。フレーム側接続部1は、サイドレール41のウェブ41aの車幅方向外側における端面41dと、ウェブ41aの下端から車幅方向内側に延びるフランジ41cの下面41eとに接する。突出部2は、フレーム側接続部1から車高方向下方に延在し、車幅方向外側に突出するように設けられる。弾性連結部6は、突出部2に連結され、車両用バッテリパック30をラダーフレーム40に懸架する。【選択図】図5
