Abstract: An electric truck that travels by electric power supplied from a battery includes a ladder frame including a pair of side rails, where the side rails face each other in a vehicle width direction, and a power supply unit including the battery, where the power supply unit is disposed between the side rails and is connected to the side rails. The side rails each have flanges having a predetermined width provided at each edge of a respective web. At least one of the flanges at a location facing a corner of the power supply unit as viewed in the vehicle width direction has a narrowed flange portion having a width smaller than the predetermined width.

Abstract: A support device configured to support a battery pack including a first battery accommodating portion arranged in a first space between a pair of side rails constituting a ladder frame of a vehicle, a second battery accommodating portion arranged in a second space below the first space and continuous with the first battery accommodating portion, and batteries accommodated in the first and second battery accommodating portions. The support device includes a frame-side bracket having first brackets extending from each of the side rails outward in a vehicle width direction and downward and a second bracket connecting the first brackets to each other below the battery pack, a battery-side bracket projecting from an end surface on an outer side in the vehicle width direction of the second battery accommodating portion outward in the vehicle width direction, and an elastic coupling portion elastically connecting the frame-side bracket and the battery-side bracket.

Abstract: An electric truck frame of an electric truck driven by electric power supplied from a battery includes a pair of side rails supporting a cab that are coupled by a plurality of cross members. The battery is disposed between the pair of side rails at a rear side of the cab. The pair of side rails include a plurality of elastic support sections that elastically support both ends of the battery in an electric truck width direction in a battery region in which the battery is disposed between the pair of side rails. The plurality of cross members are prohibited from being placed in the battery region.
