Therefore, theft of fuel can be prevented. Also, the filler pipe and the fuel tank are not linear, and the filler hose is curved and connected between them, and the protector is formed along this filler hose, preventing the protector from being displaced (regulated) )can do. Therefore, there is no fear that the lower portion of the filler hose is cut due to the position shift of the protector, and the effect of preventing fuel theft can be enhanced.

  The protector may be formed so as to be exposed from the upper part to the side part of the filler hose near the tip of the inlet pipe.

  According to such a configuration, it is possible to avoid the protector from hindering the deformation of the filler hose at the time of a vehicle collision (particularly at the rear collision). Therefore, the filler hose can be deformed at the time of a vehicle collision, and the impact can be released. In addition, even if the filler hose is exposed from the top to the side near the tip of the inlet pipe, it is usually impossible to sneak into the lower side of the vehicle and cut it (the blade etc. does not reach from the lower side of the vehicle). There is no risk of fuel theft.

  A protector is good to have a bulging part fitted in the part which the filler hose attached to this front end swells by the bulge part bulging outside formed in the front end of a filler pipe.

  According to this configuration, it is possible to more effectively prevent (regulate) the position shift of the protector. Therefore, the effect of preventing fuel theft can be further enhanced.

  The protector may include an upper covering that covers the filler hose from the upper side and a lower covering that covers the filler hose from the lower side, and the upper covering and the lower covering may be formed so as to be connectable to each other.

  According to this configuration, the protector can be easily assembled to the filler hose after the filler hose is attached to the filler pipe or the inlet pipe.

  As shown in FIGS. 1A and 1B, the automobile 100 includes a fuel tank 102 made of metal or resin. The automobile 100 also includes a metal or resin filler pipe 104 that guides the fuel supplied to the vehicle to the vicinity of the fuel tank 102, and a breather pipe 106 that discharges air in the fuel tank 102 during fuel supply. Is provided.

  The filler pipe 104 and the inlet pipe 108 (see FIG. 2) that is the entrance of the fuel tank 102 are connected by a rubber filler hose 110 having flexibility. By connecting them with a rubber filler hose 110, good assemblability is ensured, and the filler hose 110 can be deformed at the time of a vehicle collision (especially at the time of a rear collision) to release the impact. be able to.

  FIG. 2 is a diagram showing theft of fuel by cutting the filler hose 110 of FIG. As shown in FIG. 2, in the conventional vehicle, the rubber filler hose 110 is cut from the lower side of the vehicle with a blade (the cut portion is shown as “cutting portion 112”), and the thin tube 114 or the like is cut from the cut portion. There was a risk that the fuel (gasoline) could be extracted.

  FIG. 3 is a view in which a protector 116 is assembled to the filler hose 110 of FIG. Therefore, as shown in FIG. 3, in the filler hose protection structure 124 according to the present embodiment, the filler hose 110 is protected by a protector 116 having a blade-proof property. Thereby, cutting | disconnection of the filler hose 110 by a cutter can be prevented. Therefore, theft of fuel can be prevented.

  The protector 116 is formed of, for example, a plastic resin. Thereby, the increase in vehicle weight can be suppressed.

  4 is a cross-sectional view of filler hose 110 and protector 116 of FIG. As shown in FIG. 4, the protector 116 covers the lower part of the filler hose 110 from the tip of the filler pipe 104 to the tip of the inlet pipe 108. Specifically, the lower part from the bulge portion 104a bulging outward formed at the tip of the filler pipe 104 to the bulge portion 108a bulging outward formed at the tip of the inlet pipe 108 is covered. In addition, the bulge parts 104a and 108a play a role of retaining the filler hose 110 to be attached.

  Thus, in the filler hose protection structure 124, there is no portion where the lower portion of the filler hose 110 becomes one layer. Therefore, it is possible to prevent the portion protected by the protector 116 from being cut by the blade.

The upper cover body 120 and the lower cover body 122 are formed so as to be connectable to each other.

  The protector 116 a illustrated in FIG. 5A is a one-piece resin made by connecting the upper covering body 120 and the lower covering body 122 via an integral hinge 128. The protector 116b illustrated in FIG. 5B is a two-piece type resin in which the upper cover 120 and the lower cover 122 are formed separately.

  Such a protector 116 (116a, 116b) can be easily assembled to the filler hose 110 after the filler hose 110 is attached to the filler pipe 104 or the inlet pipe 108 and the ends are fixed by the clamps 130, 132. Therefore, the protector 116 does not become an obstacle when the filler hose 110 is attached to the filler pipe 104 or the inlet pipe 108, and the assembling labor is not excessively increased.

  As shown in FIG. 3, in the filler hose protection structure 124, the protector 116 is formed in the vicinity of the tip of the inlet pipe 108 so as to be exposed from the upper part to the side part of the filler hose 110. Specifically, it is formed so as to remove the upper end portion 134 shown by a virtual line in FIG.

  FIG. 6 is a diagram illustrating the behavior at the time of rear collision of the filler hose 110 and the protector 116 of FIG. As illustrated in FIG. 6, according to the above-described configuration, the protector 116 prevents the deformation of the filler hose 110 at the time of a vehicle collision (here, a rear collision (deformation of the vehicle is illustrated by “arrow D1”)). Can be avoided. Therefore, the filler hose 110 can be deformed (illustrated by “arrow D2”) at the time of a vehicle collision, and the impact can be released.

  Even if the filler hose 110 is exposed from the upper part to the side part near the tip of the inlet pipe 108, such a part usually cannot enter the lower side of the vehicle and cannot be cut (the blade or the like can reach from the lower side of the vehicle). Absent). Therefore, there is no fear of fuel theft.
