Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a tamper-proofing device for a tank cap of a small motorcycle such as a scooter.

(Prior Art) Conventionally, in this type of motorcycle, a storage compartment is disposed under the seat, a fuel tank is further disposed behind the storage compartment, and the front end of the seat is pivoted so that both can be connected by the seat. Encapsulation is being done. (For example, see Japanese Patent Application Laid-Open No. 61-282178.) In such a configuration, especially if the storage space of the storage compartment is made large, the fuel tank cap will be located on the lower surface behind the seat. There is an inconvenience that it is possible to touch the fuel tank cap by slightly lifting the end of the seat with the seat locked and inserting a hand under the seat, and opening the cap by mischief.

(Problems to be Solved by the Invention) The present invention eliminates such conventional inconveniences and makes it impossible to tamper with even if the fuel tank cap is located below the rear of the seat. .

(Means for solving the problem) In order to solve the problem, the present invention provides a motorcycle equipped with a fuel tank cap covered by the seat under the seat, in which the front end of the seat is pivoted. The fuel tank cap faces the underside of the rear seat in the closed position.
The cap is characterized in that a protruding edge is provided hanging from the lower surface of the seat for non-rotatably locking a knob consisting of a protruding piece extending in the diametrical direction on the upper surface of the cap.

(Effect of the above means) According to the above means, when the seat is locked, the knob of the fuel tank cap is locked in a non-rotatable manner by the protruding edge extending from the underside of the seat, so rotation of the cap is reliably prevented. Even if you lift the rear part of the seat slightly, it can be used as a baffle board for the cap.

(Example) A further detailed explanation will be given with reference to the drawings showing an example of implementation of the present invention.

Figure 1 shows a motorcycle in which the present invention is implemented. 1 is a seat, 2 is a front cover, 3 is a handle, 4 is a front wheel, 5 is a headlight, 6 is a floor panel, 7 is a rear wheel, and 8 is a body cover. be.

The front wheel 4 is provided with a front fender 9 housed inside the front cover 2.

FIG. 2 is a cutaway side view of the main part of FIG. 1 showing the implementation part of the present invention, and 10 is a low main frame, and the rear end of the frame 10 has an inverted L shape when viewed from the side.
The lower end front part of the rear frame 11 of the mold is joined, and the rear frame 11 has a shape that extends rearward and upward from the joining position, extends and bends, and extends substantially horizontally to the rear part. At the rear, there is a U-shaped rear stay 1 in plan view.
2 are joined together. The rear frame 11
Engine 1 is attached to the rear of the lower end by a bracket 13.
4. A unit swing type power unit 16 consisting of a transmission case 15 is connected via a link. A rear action unit 17 is connected between the transmission case 15 and the front end of the rear stay 12, and the power unit 16 is supported in a cantilever manner. 18 is an air cooler fixed to the transmission case 15.

Reference numeral 19 denotes a storage compartment including a battery storage unit 20 integrally formed in the rear part, which is a storage unit, and is disposed from the bending part of the rear frame 11 to the rear stay 12, and is open at the top and has a front bottom. was placed over the rear frame 11, and the bottom rear portion was disposed on the rear stay 12. 21 is a fuel tank whose bottom part is dropped into the rear part of the rear stay 12 and fixed with brackets 22 and 23; 24 is a fuel tank which is fixed to the rear stay 12;
A rear fender is attached to the lower part of the vehicle by brackets 25 and 26, and 27 is a tail lamp.

Furthermore, to explain in detail the implementation part of the present invention, the second
As shown in FIGS.
The front end of the seat 9 is pivotally supported by a pin 28, and the storage compartment 19, battery storage section 20, and fuel tank 21 below are covered in the closed position of the seat lock state. A tank cap 29 is provided on the upper surface of the fuel tank 21, and a knob 30 consisting of a projecting piece extending in the diametrical direction is provided on the upper surface of the cap 29. The tips of the rear carriers 31 were fixed to the upper surface of the tank 21 on both sides of the cap 29. Then, the seat 1 is in the closed position in the seat lock state as shown by the imaginary line in FIG. 3 and as shown in FIG. 4.
On the lower surface of the seat 1, a projecting edge 32 is provided hanging from the lower surface of the seat 1, bypassing the tip fixing position of the rear carrier 31 on both sides, and facing the innermost position parallel to the knob 30 located horizontally on the upper surface of the cap 29. The cap 21 was brought into contact with the tank 21, and the lower edge of the middle part was brought into contact with the upper surface of the cap 29. The seat lock device includes a seat lock rod 33 which is connected to a gate that surrounds a lid 35 of the battery storage section from a base pivoted to a boss 34 integrally formed at the bottom of both rear sides of the battery storage section 20 through both sides of the battery storage section 20. The lock rod 33 is shaped like a mold, and an arm 36 for releasing the lock is provided with the lock rod 33 in the upright position, and a pair of lock hooks 38 are provided vertically to be biased to the upright position by a spring 37 and to lock the lock rod 33 from the bottom surface of the seat 1. I made it lock.

Therefore, when trying to lift the rear part of the seat when the seat is locked, the ridge 32 on the bottom surface of the seat 1
is engaged with the fixing portion of the rear carrier 31 on both sides thereof, and is further engaged with the knob 30 of the cap 29 at the middle part, which prevents lifting of the rear part of the seat. prevents the cap 29 from rotating. Furthermore, since the lower edge of the projecting edge 32 abuts against the tank 21 and the cap 29, it supports the load applied to the rear part of the seat 1 and prevents the rear part of the seat from falling down.

5 and 6 show another embodiment of the present invention, in which the projecting edge 32 is vertically disposed behind the knob 30 of the cap 29, and its intermediate portion is locked to the knob 30 of the cap 29. I did it like that.

(Effects of the invention) According to the invention, as is clear from the above, when the seat is in the seat lock state, the protrusion locks the cap knob, so that the rotation of the cap is restricted. This makes it possible to reliably prevent the cap from being removed by mischief. Further, even if the rear end of the seat is slightly lifted in the seat-locked state, the projecting edge acts as a baffle when the cap is rotated, and the cap can be prevented from being tampered with.
