styrofoam An air-spoiler for trucks made from reinforced-film-coated compressed styrofoam

摘要

The present invention relates to an air spoiler of a truck, which is installed on a roof (R) of a cabin (C) of a truck. The air spoiler (100) is a barrel-shaped body having a soft circular shape becoming higher from a front area of the roof (R) to a rear area of the roof. The air spoiler (100) uses compressed styrofoam (11) as a material and coats an exterior thereof with a reinforced film (12). The inside of the air spoiler is formed to allow a plurality of cross type self-partitions (13) to be installed therein so as to reinforce durability and to be protected from an external force applied to the air spoiler while driving. Moreover, a rubber packing (14) is attached on an edge of a lower portion of a spoiler body for blocking water and dust and for coupling the air spoiler and the cabin roof (R) with a bolt and nut.
