The baffle 9 has an extension portion 92 extending from the front center side in the direction of exiting the vehicle body. The present invention is used to install the side storage box 8. Taking the side of the storage box 8 (left side of the vehicle body) as an example, when viewed from above the vehicle body, the bottom wall 812 of the body 81 of the side storage box 8 and the baffle 9 at least partially overlap in projection. When viewed from above the vehicle body, the bottom wall 812 of the body 81 of the side storage box 8, the baffle 9, and the side frame portion 35 of the frame unit 3 all overlap in projection. This can prevent mud and water from the ground kicked up by the rear wheel RW from spraying into the side storage box 8 or splashing onto the side frame portion 35 of the frame unit 3, thereby preventing dirty mud and water from seeping into the side storage box 8 and preventing the dirty mud and water from the ground from corroding the side frame portion 35 of the frame unit 3.

[0045] As shown in Figure 2, in a further embodiment of the locomotive 2, when the side storage box 8 is only installed on the storage box 5, for example, on the left side in the figure, the space between the right side of the storage box 5 and the side body cover 74 (right side part) of the body cover unit 7 can be further used to install an ignition coil assembly Y for generating sparks for the ignition of the internal combustion engine system.

[0046] The advantage of the present invention is that the locomotive 2 has at least a storage box 5, the side of which is provided with an installation port 53, and the installation port 53 is used to install a side storage box 8 with independent components. The storage space of the side storage box 8 is connected to the storage space of the storage box 5. In this way, on the one hand, the storage space of the storage box 5 of the locomotive 2 can be increased, and on the other hand, the manufacturing mold should not be made larger due to the increase in storage space. At the same time, the installation convenience and maintenance convenience of the side storage box 8 can be improved, thereby improving the overall storage space of the locomotive 2.

[0047] In summary, the present invention, through the above-described structure, can improve upon the deficiencies of the prior art and achieve the claimed purpose.
