Japanese Patent Laid-Open No. 11-43171

When an oil filler cap restraining cord member that projects the filler pipe outward and restrains the oil cap is placed on the filler pipe as in an automobile, the filler pipe itself has rigidity, so it is easy to fix the oil cap restraining cord member. can do.
However, some fuel tanks in saddle-ride type vehicles such as motorcycles have a fuel filler opening on one surface and a fuel cap attached to the fuel filler. In the case of a tank, since the filler pipe does not protrude outward from the fuel tank, a structure for fixing the fuel supply cap restraining cord member is required.
The present invention provides an optimum structure for fixing a fuel supply cap restraining cord member in a saddle-ride type vehicle having a fuel tank without a filler pipe.

In order to solve the above problems, a fuel device for a saddle-ride type vehicle according to the present invention detachably closes a body frame, a fuel tank supported by the body frame, and a fuel filler port formed on the upper surface of the fuel tank. A saddle riding type comprising an oiling cap and an oiling cap restraining cord member having one end connected to the oiling cap and the other end connected to a cord fixing portion provided in the vicinity of the oiling port to hold the removed oiling cap in a predetermined range In the vehicle,

The tank cover is formed on at least one of the outer edges of the tank cover in a plan view and fixed to the outer edge of the fuel tank;
It is provided on the other side where the tank cover fixing portion of the tank cover is formed in a plan view, and includes a cord fixing portion for fixing one end of the oil supply cap restraining cord member.

According to a second aspect of the present invention, in the first aspect, the oil supply cap restraining cord member is provided with a retaining portion at an end portion on the tank cover side, and the cord fixing portion is formed with respect to a part of the tank cover. A detachable cord fixing portion cover is provided, and the retaining portion is sandwiched between the cord fixing portion cover and a part of the tank cover.

According to a third aspect of the present invention, in the first or second aspect of the present invention, the tank cover is provided with a recess that forms a cap holder for placing the fuel cap removed from the fuel filler port.

According to a fourth aspect of the present invention, in the third aspect of the invention, when the oil filler cap is placed on the cap holder, a part of the oil filler cap is located outside the tank cover in a plan view. And

According to a fifth aspect of the present invention, in the above-mentioned fourth aspect, a rib connecting the tank cover fixing portion and the cord fixing portion is formed on the back side of the tank cover, and the cap holder is formed at an intermediate position of the rib. A recess is formed.

A sixth aspect of the present invention is characterized in that, in any one of the first to fifth aspects, a hose guide for guiding a hose member is integrally formed on the tank cover.

At this time, the retaining portion 54 has a larger diameter than the through hole 60a, and the ribs 68c and 69c are fixed to the annular groove 54a so that they cannot be removed.

In this way, the cord fixing portion 60 is provided with the code fixing portion cover 68 separate from the tank cover 31, and the cord fixing portion cover 68 is locked to the recess 31c on the tank cover side, whereby the retaining portion 54 is secured. As a result, the assemblability is improved. Further, since the strength of the cord fixing portion can be optimized by the separate cord fixing portion cover 68, one end of the oil supply cap restraining cord member 50 can be securely fixed at the free end of the tank cover 31.

Further, a clamp 65 and a claw 66a, which are fixing portions of the tank cover 31 with respect to the fuel tank 30, are provided at the front end portion and the left end portion, and the cord fixing portion 60 of the fuel supply cap restraining cord member 50 with respect to the tank cover 31 is opposite to these. Since the tank cover 31 is provided at the right corner of the rear end of the tank cover 31 on the side, the fixing portion of the tank cover 31 to the fuel tank 30 and the cord fixing portion 60 of the fuel supply cap restraining cord member 50 to the tank cover 31 are separated from each other. Can be formed. For this reason, since the load applied to the cord fixing portion 60 can be distributed to the tank cover 31 formed of an elastic material in a state where the oil filler cap 33 is removed, the tank cover 31 can be effectively used to fill the oil cap restraint cord. The strength and rigidity of the cord fixing portion 60 of the member 50 can be optimized to reduce the weight. Therefore, weight reduction can be achieved without increasing the number of parts, and an effective fixing structure of the oil supply cap restraining cord member 50 can be provided.

The present invention is not limited to the above embodiment, and various modifications and applications are possible within the principle of the invention. For example, the subject matter to which the invention of the present application is applied may be a saddle-ride type vehicle having a fuel tank formed with a fuel filler opening directly on the surface of the fuel tank.
