PURPOSE: A front and rear frame structure of a loading compartment of a wing-body truck is provided to reduce the cost of maintenance of a loading compartment of a wing-body truck, with improving the durability of a loading compartment frame by making the frame as one body without a welded joint part. CONSTITUTION: In a wing-body truck(A) opening and shutting cover units of a loading compartment(12) up and down by an electro hydraulic drive method, a front wall frame(10) and a rear wall frame(2) are formed by installing plural steel frame members made as one body without a welded joint part. A ceiling frame(8) is connected to the middle part of the upper end of the front and rear wall frame. Therefore, bearing a burden of load changes caused by frequent ascending and descending motions of the heavy cover units is possible, and deformation or a breakdown of the front and rear wall frame is prevented. The cost of maintenance is reduced, with the improved durability of the loading compartment frame.
