A battery pack 19 which can be mounted to and detached from a vehicle 1 includes a battery case 20 for accommodating battery cells for supplying electric power to an electric motor 21. Battery case side terminals 73 are accommodated in an insulator block 74. A plurality of ribs 94a, 95a, 96a, 94b, 95b, 96b project from a wall part of the battery case 20 to an outer surface of the insulator block 74. The insulator block 74 is provided at its outer circumference with two flanges 741, 742, and an intermediate part 743 is located between them. The outer circumferential surface of the intermediate part 743 is loosely fitted in an opening 103 of the battery case 20, with a gap G1 therebetween. Thus, the insulator block, and the connection terminals, are held in a floating state inside the battery case, without using screws or soldering. |
