A vent stringer 20 is formed by a pair of ribs 21 rising in the direction perpendicular to an inner surface 11a of a wing panel 11, and a cover 22 provided in the tip end portions of the ribs 21. With rivets 23 unexposed to an outer surface 11b of the wing panel 11, a spark is prevented from occurring in a fuel tank 30, which is provided in a main wing 10, through the rivet 23 at the time of a lightning strike. Formed by being machined integrally with the wing panel 11, the rib 21 is formed with high accuracy so as to match the curved shape of the wing panel 11. The cover 22 has only to be formed by curving a strap member so as to match the shapes of the wing panel 11 and the ribs 21.

1. A vent stringer comprising: a pair of ribs that are formed integrally on an inner surface of a wing panel forming an outer surface of a wing, the inner surface facing an inside of the wing, and that are continuous in a spanwise direction of the wing; anda cover provided so as to cover a portion between the tip end portions of the pair of ribs,wherein a flange part is formed in the tip end portions of each of the pair of ribs and the cover is abutted against the flange part,wherein the cover is configured to extend over the flange part of one rib of the pair of ribs, the space between the pair of ribs, and the flange part of the other rib of the pair of ribs. 2. The vent stringer according to claim 1, wherein the cover fastened to the flange part by using a fastening member, wherein the fastening member passes through the cover and the flange part. 3. The vent stringer according to claim 1, wherein the rib is formed by being machined from a metallic base material that constitutes the wing panel. 4. The vent stringer according to claim 1, wherein the cover is formed by arranging a plurality of cover members in the spanwise direction of the wing and by joining the cover members to each other;flanges rising toward an outside of the vent stringer are provided in the end portions of the cover members adjacent to each other in the spanwise direction of the wing; andthe flanges of the cover members adjacent to each other are joined to each other by using a joint pin having an axis line in the spanwise direction of the wing. 5. The vent stringer according to claim 2, wherein the cover is formed by arranging a plurality of cover members in the spanwise direction of the wing and by joining the cover members to each other;flanges rising toward an outside of the vent stringer are provided in the end portions of the cover members adjacent to each other in the spanwise direction of the wing; andthe flanges of the cover members adjacent to each other are joined to each other by using a joint pin having an axis line in the spanwise direction of the wing. 6. The vent stringer according to claim 3, wherein the cover is formed by arranging a plurality of cover members in the spanwise direction of the wing and by joining the cover members to each other;flanges rising toward an outside of the vent stringer are provided in the end portions of the cover members adjacent to each other in the spanwise direction of the wing; andthe flanges of the cover members adjacent to each other are joined to each other by using a joint pin having an axis line in the spanwise direction of the wing. 7. The vent stringer according to claim 1, wherein a total area of the cover is less than a total area of the wing panel. 8. The vent stringer according to claim 1, wherein the vent stringer includes an internal space at least partially defined by the wing panel, the pair of ribs, and the cover, and the vent stringer is configured to enable passage of air through the internal space from outside a fuel tank into the fuel tank. 9. The vent stringer according to claim 1, wherein the vent stringer includes an internal space at least partially defined by the wing panel, the pair of ribs, and the cover, andwherein the cover is fastened to the flange parts of the ribs by a fastening member such that the fastening member is at least partially located outside of the internal space and within an interior space of a main wing. 10. The vent stringer according to claim 9, wherein the cover is fastened to the flange parts at a fastening location separated from a neutral axis of the vent stringer, andthe fastening location is on an opposite side of the neutral axis from the wing panel. 11. An aircraft main wing comprising: a wing panel forming an outer surface of the wing; andthe vent stringer according to claim 1. 12. A vent stringer comprising: a wing panel, wherein the wing panel comprises an outer surface and an inner surface, the outer surface forming the outer surface of a main wing;at least one pair of ribs, wherein the ribs are formed integrally on the inner surface of the wing panel and are formed continuously in a spanwise direction of the main wing; anda cover, wherein the cover is configured to attach to the pair of ribs between the tip end portions of the pair of ribs,wherein a flange part is formed in the tip end portions of the ribs and the cover is abutted against the flange part,wherein an interior space is defined by the wing panel on one side, the pair of ribs opposite each other and both adjacent to the wing panel, and the cover opposite the wing panel,wherein the cover is configured to extend over the flange part of one rib of the pair of ribs, the space between the pair of ribs, and the flange part of the other rib of the pair of ribs. 13. An aircraft main wing comprising: a wing panel forming an outer surface of the wing; anda vent stringer, the vent stringer comprising:a wing panel, wherein the wing panel comprises an outer surface and an inner surface, the outer surface forming the outer surface of a main wing;at least one pair of ribs, wherein the ribs are formed integrally on the inner surface of the wing panel and are formed continuously in a spanwise direction of the main wing; anda cover, wherein the cover is configured to attach to the pair of ribs between the tip end portions of the pair of ribs,wherein a flange part is formed in the tip end portions of the ribs and the cover is abutted against the flange part,wherein an interior space is defined by the wing panel on one side, the pair of ribs opposite each other and both adjacent to the wing panel, and the cover opposite the wing panel, wherein the cover is configured to extend over the flange part of one rib of the pair of ribs, the space between the pair of ribs and the flange part of the other rib of the pair of ribs.
