BATTERY CASE

PROBLEM TO BE SOLVED: To provide a battery case that can prevent dropout of a bolt and is enhanced in durability.SOLUTION: When a bolt 32 is loosened due to a cause such as shock or vibrations and thus the bolt 32 is about to move in a direction in which the bolt 32 is disengaged, a pair of protrusions 2410 constituting a first restricting portion 24A come into contact with a flange 3204 of the bolt 32, thereby restricting further movement of the bolt 32 and preventing dropout of the bolt 32. Furthermore, when a vehicle side-crashes, a load directing inwards in the vehicle width direction is applied to inclined surface portions 2204 positioned on both sides in the vehicle width direction of a cover 22, so that the cover 22 is deformed inwards in the vehicle width direction, and a restricting member 24 also tends to move inwards in the vehicle width direction due to deformation of the cover 22. However, as a base portion 2408 constituting a second restricting portion 24B abuts against the side surface of a bolt head portion 3202, movement of the restricting member 24 in the direction approaching to an upper holder 20 is restricted, so that the restricting member 24 can be suppressed from hitting against the upper holder 20.SELECTED DRAWING: Figure 4 【課題】ボルトの脱落を防止し耐久性の向上を図る。【解決手段】衝撃や振動などの原因によりボルト３２が緩み、ボルト３２が外れる方向に移動しようとすると、第１の規制部２４Ａを構成する一対の凸部２４１０がボルト３２のフランジ３２０４に当接することでそれ以上のボルト３２の移動が規制され、ボルト３２の脱落が防止される。また、車両が側突した場合、カバー２２の車幅方向両側に位置する傾斜面部２２０４に対して車幅方向内側に向かう荷重が入力し、カバー２２が車幅方向内側に変形し、規制部材２４もカバー２２の変形により車幅方向内側に移動しようとする。しかしながら、第２の規制部２４Ｂを構成する基部２４０８がボルト頭部３２０２の側面に当接することで規制部材２４がアッパホルダ２０に近づく方向への移動が規制され、規制部材２４がアッパホルダ２０にぶつかることを抑制できる。【選択図】図４
