[0049]
If the battery 48 is arranged in this way, the bottom center of gravity can be achieved while utilizing the empty space, and the lower part of the seat 21 occupies the volume for the large helmet H, and the functional parts are likely to be arranged rearward. By arranging the battery 48 on the front side of the helmet box 32, the weight distribution before and after the vehicle can be favorably performed, and the cooling air can be efficiently introduced.
[0050]
Incidentally, in an underbone type motorcycle in which the helmet box 32 is not arranged under the seat 21, there is a sufficient space near the bottom of the seat 21, so that the functional parts are arranged in this portion. Therefore, the battery 48 and the like are also high and the center of gravity tends to be high. In addition, although there is a scooter type vehicle in which the fuel tank 42 is arranged at this position, the engine is a unit swing type arranged on the rear wheel 4 side, and the form is different.
[0051]
