The storage box 13 has an open top surface and is large enough to store a helmet 14. A battery box 15 is arranged in front of the storage box 13.

The open upper surface of the storage box 13 is covered by a box cover 17 that is pivotally supported by a hinge 16 so as to be openable and closable. In the closed position of the box cover 17, a locking device 18 is activated.

A fuel tank 19 is arranged below the seat 11. The rear end 19a of this fuel tank 19 is connected to the pillion seat 1.
2, and an injection port 20 is opened on the upper surface. Note that reference numeral 21 is a cowling that covers the front of the head vibro, and reference numeral 22 is a body cover that covers both sides below the seat 11 and pillion seat 12.

The article storage device 23 includes the storage box 13, the hinge 16, the box cover 17, and the like. Of these, the box cover 17 is shown in FIG.
) and (B), the inner plate 24 and the outer plate 25
It is constructed into a double structure using. The inner plate 24 and the storage box 13 are connected by a hinge 16, and the inner plate 24 is provided so as to be able to come into airtight contact with the opening edge of the storage box 13.

The outer plate 25 has mounting ribs 26 and mounting screws 2 on the inner plate 24.
7. That is, as shown in FIG. 1(C), the mounting rib 26 is formed to have a substantially U-shaped cross section;
For example, both sides are welded to the inner surfaces of the outer panels 2 and 5. The outer plate 25 is attached to the inner plate 24 by fixing the top of the attachment rib 26 and the inner plate 24 with the attachment screws 27.

The outer plate 25 is attached to the inner plate 24 at a predetermined distance using the mounting ribs 26, so that a space 28 is formed between the inner plate 24 and the outer plate 25. This space 28 is
It communicates with an opening 29 formed around the entire circumference of the box cover 17 . Due to the air layer existing within this space 28,
Insulating and cooling effects are provided within the storage box 13.

That is, even if the outer panel 25 of the article storage device 23 is heated by direct sunlight, the air layer within the space 28 functions as a heat insulating material, and a heat insulating effect is provided within the storage box 13.

Further, when the outer panel 25 is heated, air in the space 28 is convected, and the opening (vehicle rear side opening) 2 located at a relatively low position
Cold air flows in from 9 to cool the inner plate 24, and hot air flows out from an opening 29 located at a relatively high position (an opening on the front side of the vehicle) to provide a cooling effect within the storage box 13.

Further, while the vehicle is running, the running wind flows in and out through the opening 29 and blows through the space 28, so that the cooling effect is further improved.

Due to the heat insulating effect and cooling effect as described above, even if the box cover 17 is heated by direct sunlight, it is possible to prevent heat damage to the articles stored in the storage box 13.
