PROBLEM TO BE SOLVED: To provide a structure for a power supply device in which connection terminals of a battery case are held in a floating state by the battery case without using screws or soldering.SOLUTION: A battery pack 19 freely attachable/detachable to/from a vehicle 1 includes a battery case 20 for housing battery cells to supply power to a traveling electric motor 21. Battery case-side terminals 73 are housed in an insulating block 74. A plurality of ribs 94a, 95a, or the like project from a wall part of the battery case 20 and are arranged along an outside surface of the insulating block 74. Two flanges 741, 742 and an intermediate part 743 sandwiched between them are formed on the outer periphery of the insulating block 74. The outer peripheral surface of the intermediate part 743 is loosely fitted into an opening 103 of the battery case 20 with a gap G1 therebetween. |
