PURPOSE: A wing body of a truck is provided to improve endurance, and to cut down repair and management expenses by minimizing cracks or torsion of the wing body during traveling for a long time. CONSTITUTION: Thermal insulating and sealing polyurethane foam is injected to the inner surface of a wing body(20) for a truck, and the polyurethane skin(60) is spread by foaming and hardening. A wing gate(30) is supported and fixed in the ceiling of the wing body, and opened and closed in the upper part of a loading compartment(10). A front vertical panel(22) is formed in a center beam(40) of the ceiling to prevent the wing body from being distorted against vibration or deformation of the vehicle body. Plural center wires(50) are installed between the front vertical panel and a rear vertical frame(24). Breakage of articles is prevented with shutting off cargo in the loading compartment, and articles are transported safely with installing the wing gate between the front vertical panel and the rear vertical frame. The endurance of the wing body is improved with preventing damage.
