As shown in FIG. 3, the first bracket 21 ₁ is welded to the front portion of the frame rear intermediate portion 5, and the bottom wall of the storage box 14 is fixed thereto by the bolt 1. A seat 22 is joined to the front end of the upper part of the storage box 14 via a hinge 23 so that the seat 22 can rotate backward and upward. The second bracket 20 ₂ and the third bracket 20 ₃ are welded to the cross bar 5a and the frame rear portion 6, and the fuel tank 15 is fixed to the bolts 21 ₂ and 2 by these.
It is fixed by 1 ₃ .

As shown in FIGS. 4 to 6 and 8, the storage box 14 has at least a volume capable of storing the helmet H and has an open upper surface, and an auxiliary machine that covers the upper surface of the fuel tank 15 as an auxiliary machine. It is molded of synthetic resin integrally with the machine cover 25. A water drain hole 19 is provided in the bottom wall of the storage box 14. The auxiliary machine cover 25 is provided with a cap hole 27 through which the cap 26 provided on the fuel filler port of the fuel tank 15 projects. In addition, an endless bearing convex strip 29 is formed on the peripheral edges of the storage box 14 and the auxiliary device cover 25, and an endless positioning groove 30 formed on the peripheral edge of the bottom surface of the bottom plate 22a of the seat 22 is provided with the seal member 31. By engaging through the above, the closed position of the seat 22 that covers the storage box 14 and the accessory cover 25 is defined. The bottom plate 22a of the seat 22 is made of synthetic resin, and an L-shaped striker 33 made of metal, which projects downward through the through hole 32 of the accessory cover 25 at the closed position, is insert-coupled to the central portion of the bottom plate 22a. There is.

A seat lock device 34 is fixed to the fuel tank 15 of the second bracket 20 ₂ with a bolt 21 ₂ just below the accessory cover 25. The seat lock device 34 has a pair of left and right stud bolts 35 protruding from its upper surface.
Is inserted into a bolt hole 36 of the accessory cover 25, and a cap nut 37 is screwed on. In this way, the accessory cover 25
It is supported by the second bracket 20 ₂ via the seat lock device 34. The seat lock device 34, as is known,
The striker 3 is provided with a latch 38 which is constantly biased to the lock position by a spring and an operation cable 39 which can retract the latch 38 to the unlock position.
3 is locked to lock the seat 22 in its closed position. The operation cable 39 is operated by a cylinder lock key (not shown).

As shown in FIGS. 5 to 7, a first labyrinth 40 is provided between the accessory cover 25 and the seat bottom plate 22a.
_{The first} and first labyrinths 40 ₂ are provided with the through hole 32 sandwiched in the front and rear. The first labyrinth 40 ₁ has a through hole 3
Auxiliary equipment cover 2 so that it extends in the left-right direction of the vehicle body immediately before 2
5, a recessed groove 41 formed over the entire width of the storage box 14 (see FIG. 4), and a rib 42 integrally provided on the bottom plate 22a of the seat 22 so as to protrude into the recessed groove 41. The drainage hole 43 is formed in the bottom wall of the concave groove 41.
Is provided. The first labyrinth 40 ₂ has a through hole 3
The U-shaped inner rib 44 integrally formed on the upper surface of the accessory cover 25 so as to extend along the left and right side edges and the rear edge of
And an outer rib 45 integrally formed on the lower surface of the seat bottom plate 22a so as to surround the inner rib 44.

Further, on the upper surface of the accessory cover 25, the inner rib 44 is bent from the front end of the inner rib 44 in the left-right direction of the vehicle body, and is bent rearward to extend so as to surround the fuel filler cap 26. The low enclosure wall 46 is integrally formed, which can prevent the fuel overflowing on the accessory cover 25 from flowing into the storage box 14 side when the fuel tank 15 is refueled. In order to discharge such fuel to the outside, an escape hole 47 is provided in the lowest portion inside the surrounding wall 46.

On the other hand, on the lower surface of the bottom plate 22a of the seat 22,
A pair of support cylinders 48 surrounding the pair of left and right cap nuts 37 are integrally formed on both left and right side surfaces of the outer rib 45, and when the weight of the occupant is added to the seat 22,
These support cylinders 48 are supported on the upper surface of the accessory cover 25. The support cylinder 48 also contributes to prevent the cap nut 37 from falling off.

Next, the operation of this embodiment will be described.

When the seat lock device 34 is unlocked and the seat 22 is rotated upward with the hinge 23 as a fulcrum, the storage box 14 is opened and the filler cap 26 is exposed. It is possible to take in and out of luggage and refuel. At that time, the auxiliary machine cover 25 integrated with the storage box 14 is attached to the seat lock device 34.
Moreover, since the fuel tank 15 is covered, the appearance can be kept good.

Next, when the seat 22 is tilted to the closed position, the striker 33 automatically engages with the latch 38 of the seat lock device 34 through the through hole 32 of the auxiliary equipment cover 25 and the seat bottom plate 22a. The positioning groove 30 engages with the bearing ridge 29 of the storage box 14 and the auxiliary device cover 25 via the seal member 31. Therefore, the seat 22 is locked at the closed position, and it is possible to prevent dust and rainwater from entering the storage box 14 and the upper surface of the accessory cover 25 from around the seat bottom plate 22a.

However, since the auxiliary machine cover 25 has a through hole 32 through which the striker 33 passes inside the endless bearing convex strip 29, dust is passed through the through hole 32 in the storage box 14 and the auxiliary machine cover. 25, the first labyrinth 40 ₁ and the first labyrinth 40 ₂ are formed between the seat bottom plate 22a and the auxiliary equipment cover 25 with the through hole 32 in front and back. The entry of dust from the hole 32 into the storage box 14 is performed by the first labyrinth 40 ₁ , and the entry of dust from the through hole 32 to the upper surface of the accessory cover 25 is performed by the first labyrinth 40.
Each can be prevented by ₂ . Moreover, the first labyrinth 40 ₁ has the concave groove 41 formed in the accessory cover 25.
And the seat bottom plate 22a so as to protrude into the groove 41.
The second labyrinth 402 is a U-shaped inner rib 44 integrally projecting on the upper surface of the accessory cover 25, and the second labyrinth 40 ₂ surrounds the inner rib 44. Since the outer rib 45 is integrally formed on the lower surface of the bottom plate 22a of the seat 22, the dedicated sealing member is not required, and the dustproof structure of each is simple.

The present invention is not limited to the above embodiments, and various design changes can be made without departing from the scope of the invention. For example, a plurality of sets of concave grooves 41 and ribs 42 that form the first labyrinth 40 ₁ and the second labyrinth 40
It is also possible to provide a plurality of sets of the inner ribs 44 and the outer ribs 45 that form the element ₂ . The seat can also be hinged to a bracket projecting on the upper surface of the vehicle body. The present invention can also be applied to motorcycles and three- and four-wheeled buggy vehicles.
