The protector 14 comes into surface contact with and covers the upper parts of the protruding surfaces of the two first protrusions 21b and the upper parts of the protruding surfaces of the second protruding part 21c.

As shown in FIG. 3, the protector 14 is disposed along the second upper surface portion 21 of the inner lid 20 so as to be inclined downward toward the outside in the vehicle width direction. The upper edge of the protector 14 is located inward in the vehicle width direction from the tip of the flange 13c on the upper edge of the lid outer 13 and inward in the vehicle width direction from the uppermost point T of the cap 31. There is. Further, the lower edge of the protector 14 is located further outward in the vehicle width direction than the uppermost portion T of the cap 31. Both ends of the protector 14 in the front-rear direction are located on the outer side of the filler neck 30 in the front-rear direction. The protector 14 is designed so that, for example, even when the vehicle is tilted back and forth at a generally assumed inclination angle with respect to the ground, both ends of the protector 14 in the front and back direction are located on the outside of the filler neck 30 in the front and back direction. Even if the vehicle tilts to the left or right after the generally assumed inclination angle with respect to the ground, the upper end of the protector 14 is inward in the vehicle width direction with respect to the uppermost point T of the filler neck 30, and the lower end of the protector 14 is It is preferable that the filler neck 30 is designed to be located outward in the vehicle width direction with respect to the uppermost point T of the filler neck 30.

The filler neck storage structure 10 according to the first embodiment is configured as described above. As shown in FIG. 3, in the filler neck storage structure 10, a protector 14 is attached to the inside of the extending plate portion 21a of the inner lid 20 in the vehicle width direction. Further, as shown in FIG. 2, the protector 14 is located above the uppermost portion T of the cap 31. In the filler neck storage structure of this embodiment, the protector 14 is located between the upper edge of the flange 13c of the lid outer 13 and the uppermost point T of the cap 31. This positional relationship allows the protector 14 to receive water that has entered between the upper inner edge 1a of the opening 15 and the upper edge of the lid 2, and allows water to flow inward in the vehicle width direction from the uppermost point T of the cap 31. can be prevented from being exposed. In this embodiment, the protector 14 is also located between the flange on the upper inner edge 1a of the opening 15 and the uppermost portion T of the cap 31. As a result, even if the cooling water that has flowed down along the side surface of the vehicle body 1 falls along the flange of the upper inner edge 1a of the opening 15, the water will flow inward in the vehicle width direction from the uppermost point T of the cap 31. It is possible to prevent this from happening.

Further, the protector 14 extends downward toward the outside in the vehicle width direction. Therefore, the water received by the protector 14 is guided to the passage (first passage L1 and second passage L2) provided between the pair of first protrusions 21b while moving downward on the protector 14. (see arrow in Figure 2). Since the guided water passes through the passage, water can be stably discharged from between the protector 14 and the lid inner 20.

As shown in FIG. 3, the lower end of the protector 14 is located further outward in the vehicle width direction than the uppermost portion T of the cap 31. Therefore, water dripping from the lower end of the protector 14 hits the end surface of the cap 31 (outside the uppermost point T in the vehicle width direction). Since the water flows along the end surface of the cap 31 and downward toward the outside in the vehicle width direction, it is possible to prevent the filler neck 30 from being covered with water.

The lid inner 20 of the filler neck storage structure 10 is formed with a pair of first protrusions 21b that protrude inward in the vehicle width direction. The pair of first protrusions 21b can reinforce the inner lid 20. Further, by attaching the protector 14 to the pair of first protrusions 21b, the lid inner 20 can be reinforced by the protector 14. Furthermore, since the passage is formed by the pair of first protrusions 21b for attaching the protector 14, there is no need to set up a separate structure for forming the passage.

Furthermore, a second protrusion 21c is provided between the pair of first protrusion 21b. The lid inner 20 can be reinforced by the second protrusion 21c. Furthermore, by providing the protector 14 on the second protrusion 21c, the protector 14 can also be supported by the second protrusion 21c.

In addition, since the second protrusion 21c is located at the top of the cap 31, the water flowing through the passage avoids the top of the cap 31 in the longitudinal direction of the vehicle. It is possible to further prevent water from getting on the inside.

Further, a hem portion 21d of the second protruding portion 21c extends in the front-rear direction, and the front and rear ends of the hem portion 21d are located on the outer side of the tip of the filler neck 30 in the front-rear direction. Due to the hem portion 21d, the water guided into the first passage L1 and the second passage L2 without dripping from the lower end of the protector 14 drips from the positions of both ends of the hem portion 21d in the front and back direction, and the cap 31 can be prevented from being covered with water. Further, the lower end portion of the hem portion 21d is located on the outer side in the vehicle width direction with respect to the cap 31. Therefore, it is possible to further prevent water dripping from the lower end of the hem portion 21d from covering the cap 31.

The protector 14 of the filler neck storage structure 10 is a plate member made of synthetic resin. Since the protector 14 having this shape is not bent, it is difficult to break even when an external force is applied, and manufacturing costs can be reduced. Furthermore, even when the lid 2 is open, there is no risk of injury due to the upper edge of the protector 14. Further, as shown in FIG. 3, since the upper edge of the protector 14 is located inward in the vehicle width direction than the upper edge of the flange 13c of the lid outer 13, injuries caused by the upper edge of the flange 13c of the lid outer 13 can be prevented. This makes it even safer.

A filler neck storage structure according to a second embodiment of the present invention will be described based on FIGS. 5 and 6. The second embodiment differs from the above-described first embodiment in that the protector 14 is attached to the upper wall 17 of the recess 11. In other configurations, those that are considered to be the same as those in the first embodiment are given the same reference numerals, and the explanation thereof will be omitted.

As shown in FIGS. 5 and 6, in the filler neck storage structure according to the second embodiment, a support portion 11c that protrudes outward in the vehicle width direction is formed at the upper part of the upper wall portion 17 of the recess 11. The protector 14 is attached to the support portion 11c so as to be located above the filler neck 30.

In the filler neck storage structure according to the second embodiment, as shown in FIG. 6, when the lid 2 is closed, the lower part of the protector 14 is connected to the upper part of the pair of first protrusions 21b of the lid inner 20. It is located near or in contact with the upper part of the second protrusion 21c. Furthermore, the protector 14 is located between the flange 13c of the lid outer 13 and the filler neck 30. Therefore, in the second embodiment as well, as in the first embodiment described above, water that enters between the upper inner edge 1a of the opening 15 and the upper edge of the lid 2 is not received by the protector 14. This makes it possible to prevent water from getting on the inside of the tip of the filler neck 30 in the vehicle width direction.
