a partition wall portion which extends in a vehicle width direction in the vehicle front portion and demarcates a vehicle cabin inside space from a power chamber;
a motor arrangement portion formed by a part of the partition wall portion that bulges toward the vehicle cabin inside space, and at least a part of the traveling motor installed on outside of the vehicle cabin inside space is capable of being arranged in the motor arrangement portion;
a reinforcement structure which extends from an upper portion of the motor arrangement portion towards a vehicle rear wherein the reinforcement structure is inclined so that a rear portion of the reinforcement structure is positioned lower in an up-down direction of the vehicle toward the vehicle rear; and
