A battery device (33) is provided with first to fourth battery packs (61, 71, 81, 91), first to fourth rear brackets (62, 72, 82, 92), and first to fourth fixing bolts (B1 to B4). The first to fourth battery packs (61, 71, 81, 91) are stacked in the vertical direction. The first to fourth rear brackets (62, 72, 82, 92) are attached to the rear surfaces (T1) of the first to fourth battery packs (61, 71, 81, 91). First to fourth fixing bolts (B1 to B4) fix the first to fourth rear brackets (62, 72, 82, 92), respectively. In a plan view of the battery device (33), the top surfaces of the first to fourth fixing bolts (B1 to B4) are recognizable.
蓄电池装置(33)具备第一~第四蓄电池组(61、71、81、91)、第一~第四后托架(62、72、82、92)、以及第一~第四固定螺栓(B1~B4)。第一~第四蓄电池组(61、71、81、91)沿上下方向层叠。第一~第四后托架(62、72、82、92)安装于第一~第四蓄电池组(61、71、81、91)各自的后表面T1。第一~第四固定螺栓(B1~B4)将第一~第四后托架(62、72、82、92)分别固定。在俯视蓄电池装置(33)时,第一~第四固定螺栓(B1~B4)各自的头顶面能够辨识。
