A battery pack can be protected while suppressing a decrease in efficiency of maintenance work for vehicle parts around the battery pack. A pack outer cross, which is a skeleton member, is fixed to a bottom surface of a case of a battery pack and extends across the width of the case. The extension 23, which is an extended skeleton member, is detachably assembled to both ends in the vehicle width direction of the outer pack cross 21A, and protrudes outward in the vehicle width direction from both ends in the vehicle width direction of the case 11.
