Each member is covered by the under-seat cover 49. As is clear from FIG. 3, the floor panel 2
The rear portion of the second convex portion 22a is obliquely cut, and the lower seat portion of the under-seat cover 49 is joined to the diagonal cut portion of the convex portion 22a so as to be continuous with the floor panel 22, thereby enhancing the sense of unity of the body cover. ing. Further, since the under-seat cover 49 is joined to the floor panel 22 at a position higher than the floor surface, sand, mud, etc. on the floor surface will not enter the vehicle body through the joint.
A plurality of positioning pieces 50 are provided on the lower end of the seat lower cover 49.
And a plurality of fixing portions 51 are integrally provided, and these fixing portions 51 are bolted to the fixing portion 52 projecting inwardly of the oblique cutting portion of the convex portion 22a as shown in FIG. .

In FIGS. 4, 6, and 8, a main stand 55 is arranged below the seat 3 so as to be located between the under guard plate 32 and the power unit 35. As is apparent from FIG. 4, the main stand 55 has stays 57a and 57b with respect to the cross member 56 fixed between the pair of down pipes 13L and 13R.
A rotary shaft 58 rotatably attached through the rotary shaft 58, leg portions 59L and 59R fixed to the rotary shaft 58, and a cross member 60 fixed between the leg portions.
It is swingably provided between a use position shown by a chain line in the drawing and a storage (unused) position shown by a solid line. Legs 59
Return springs 62L and 62R are stretched between the L and 59R and the stays 57a and 57b. A stopper 63 that abuts the main stand 55 at the storage position is attached near the rear rising portions of the down pipes 13L and 13R, and a rubber 64 as a cushioning material is attached to the abutting surface of the stopper 63. There is. The main stand 55 arranged between the under guard plate 32 and the power unit 35 also serves as a protective member for protecting auxiliary devices such as a fuel pump 65 arranged above it, the engine 34, and the frame pipe. To work.

The main stand 55 has a footrest arm 61 protruding from the leg 59L to the outside of the vehicle body. This footrest arm 61
When the main stand 55 is in the retracted position, the foot rest 61a of the footrest portion 61a is in front of the introduction port 45 formed in the lower cover 8b of the rear cover 8 and overhangs the rear cover 8 as shown in FIGS. It is arranged so as to be located inside the vehicle body with respect to the outer edge of 8b. According to this arrangement, when the main stand 55 is not used, the footrest portion 6 of the footrest arm 61 is
Since 1a is stored below the projecting portion 8b of the rear cover 8, it does not interfere with the rider. Further, when the main stand 55 is erected, it is sufficient to carry the foot F below the overhanging portion 8b of the rear cover 8 and place it on the footrest portion 61a as shown in FIG. I will never come.

2 and 8, the down pipes 13L, 13
Gusset plate 33 welded to the rear rising portion of R
A trunk frame 66 extends from the rear of the vehicle body, and a rear trunk 67 is mounted on the trunk frame 66. As is apparent from FIG. 9, the trunk frame 66 has a substantially U-shape, is fixed to the gusset plate 33 at its front end portion, and further, via support pipes 68L and 68R welded to its intermediate portion. Down pipe 13
It is fixed to L and 13R. For example, three fixing portions 69 are welded to the frame 66 and the support pipes 68L and 68R, and the rear trunk 67 is bolted to the fixing portions 69 with three mounting holes 70 provided at the bottom thereof. To be done.

As shown in FIG. 10, the rear trunk 67 is composed of an upper case 67U and a lower case 67L, and the respective cases are integrated at the open ends thereof to form a trunk chamber (storage chamber). They are fixed and fixed to each other by being screwed with fixing portions 71U and 71L provided at several places on the periphery. A plurality of ribs 72U are provided laterally on the outer surface of the upper case 67U, and
A plurality of ribs 72L are integrally provided on the bottom surface of L in the vertical direction and the horizontal direction, respectively.
This improves the rigidity of the trunk body.

The rear trunk 67 mounted on the trunk frame 66 is surrounded by the upper cover 8A of the rear cover 8. As shown in FIG. 9, the upper cover 8A is bolted to a plurality of nuts 74 welded to the trunk frame 66 at a plurality of mounting holes 73 formed at the lower end of the upper cover 8A. Fixed against. A tail light assembly 76 is attached to the stay 75 welded to the rear end of the trunk frame 66. The taillight assembly 76 integrally includes a taillight 77 and a number guard 79 to which a license plate 78 is attached. Lower cover 8B of rear cover 8
Has, for example, two projecting pieces 80 at the upper edge and a projecting piece 81 at the upper rear end, and these projecting pieces 80, 81 serve as the upper cover 8A.
And a rear end portion mounting hole 84, which are fitted in the fitting hole 82 formed in the hole and the fitting hole 83 formed in the number guard 79, respectively.
Is bolted to the mounting hole 85 formed in the number guard 79. The front end of the lower cover 8B has a fourth
As described in the figure, the boss 53 fits the vehicle body frame.

In FIG. 8, the rear trunk 67 is provided so as to be opened rearward of the vehicle body while being housed in the rear cover 8, and the opening edge thereof is slightly projected from the body (rear cover 8). The lid 91 that opens and closes this opening is
At the lower end of the trunk frame 6 via a hinge 92.
6, a key 93 is provided at the center of the upper end. A seal member 94, which is in pressure contact with the lid 91 in the closed state, is attached to the opening edge of the rear trunk 67 that protrudes from the body, thereby improving the waterproofness of the rear trunk 67. Further, as is clear from FIG. 13, a groove 96 is defined by the edge of the upper cover 8A, the rear trunk 67 and the sealing member 94, and this groove 96 acts as a guide groove for discharging rainwater.

As is clear from FIG. 4, the rear cover 8 is formed wider than the step floor 7. The rear trunk 67 accommodated in the rear cover 8 is arranged such that the outer wall thereof is close to the inner surface of the rear cover 8. According to this, the capacity of the trunk chamber of the rear trunk 67 can be improved, the rear trunk 67 can be used as a reinforcing member against the deformation of the rear cover 8, and the rigidity of the rear cover 8 can be improved without using a dedicated reinforcing member. Become.

A muffler 86 is located below the right side of the rear trunk 67 with respect to the vehicle traveling direction, as shown in FIG.
To prevent heat from this muffler 86, the muffler 86
A heat insulating material 87 is attached to the trunk bottom plate above. As shown in FIGS. 12 (A) and 12 (B), the heat insulating material 87 is composed of a glass worm 88 and a silver paper 89 covering the glass worm 88, and by caulking rivets 90 at several points with respect to the trunk bottom plate. Fixed.
By the action of this heat insulating material 89, the heat from the muffler 86 can be blocked and the trunk bottom plate can be protected from the heat. An air layer 95 is formed between the heat insulating material 89 and the trunk bottom plate due to the presence of the rib 72L, and the heat insulating effect can be further improved by the air layer 95.

In the above embodiment, the step floor 7, the rear cover 8, the floor panel 22, the rear trunk 67, etc. are made of resin, and the frame members such as the main pipe 12, the down pipes 13L, 13R, the seat pipe 19, the trunk frame 66, etc. Shall be formed of metal.

As described above, in the arrangement structure of the main stand in the scooter type vehicle according to the present invention, the main stand having the rotation support shaft near the rear end of the plate-shaped (planar) guard member that covers the lower side of the fuel tank. Is configured to be positioned below the electrical component member in a state of being stored in the storage position.

Therefore, even if the vehicle rides on an obstacle such as a curb while the vehicle is traveling, the main stand serves as a protector and protects electric components (fuel pump, auxiliary devices, etc.) located above the protector.

Further, the traveling wind passes through the main stand and reaches the electric component member, and cools the electric component member that generates heat. Therefore, the deterioration of the electrical component due to heat generation can be prevented, and the original function can be reliably ensured.
