A drive shaft (18) of a dump truck (1) is linked both to an electric motor (43) and to tires (11, 12) via universal joints. The drive shaft (18), in a state where there is no load on a body (30), is inclined at a first crossing angle (α1) so that the tire (11, 12) side of the drive shaft faces downward in a horizontal direction, and in a state where the load on the body (30) is the maximum within an allowable load weight range, the drive shaft (18) is inclined at a second crossing angle (α2) so that the tire (11, 12) side of the drive shaft (18) faces upward in the horizontal direction. |
