Patent ID: 8561741

Claim:
A vehicle air guide duct structure comprising: left and right side-wall ducts provided on left and right sides of an equipment to be cooled and extending in a longitudinal direction of a vehicle body for guiding air in front of a vehicle as cooling air to the equipment to be cooled; elastically deformable left and right seal sections projecting outward from respective inner wall surfaces of the left and right side-wall ducts toward side-edge front surfaces of the equipment to be cooled, the seal sections extending up to the side-edge front surfaces while being separated by a predetermined distance from the side-edge front surfaces toward a front of the vehicle; a plurality of reinforcing ribs provided on a front wall surface or a rear wall surface of each of the left and right seal sections except a distal end part of each seal section, the reinforcing ribs having a substantially triangular shape and connecting the front wall surface or the rear wall surface of each of the seal sections to the inner wall surface of a corresponding one of the left and right side-wall ducts; wherein each of the side-wall ducts and a corresponding one of the seal sections are formed from a single-piece rubber material, wherein the reinforcing ribs provide each of the seal sections with a rigidity such that, when subjected to a traveling air pressure while the vehicle is traveling, the seal sections undergo elastic deformation and come into contact with the side-edge front surfaces, and when the vehicle is idling, the distal end parts of the seal sections remain separated from the side-edge front surfaces, and wherein the side-wall ducts have: attachment flaps projecting in a direction substantially orthogonal to a direction in which the side-wall ducts extend; and interlocking parts provided on the attachment flaps, wherein the interlocking parts have longitudinal interlocking parts capable of interlocking with top and bottom areas of oblong holes provided on the sides of the vehicle body and extending in the vehicle width direction.
