Description of the Related Art Conventionally, as a carrier for a truck mounted on the rear part of a vehicle body of a truck, between a side wall, a double-sided door pivotally supported at or near the rear end of the side wall, and between upper ends of the side walls. There is known a van-type carrier having a roof erected on a vehicle. In this carrier, front walls protruding above the cab of the truck are provided at the front ends of both side walls. For this reason, a rectifying member for reducing the air resistance during traveling of the truck is provided on the front wall to reduce the air resistance at the front of the loading platform. On the other hand, the air that has flowed to the rear of the load along the outer wall of the load forms a vortex behind the double door when flowing from the rear end of the outer wall to the rear of the load. In order to solve this problem, a rear structure of a van-type truck in which a rectifying member is provided also at the rear of the loading platform has been proposed (Japanese Utility Model Laid-Open No. 4-5187). In the rear structure of this van type truck, a guide panel, which is a rectifying member, is attached to a rear wall, and the guide panel gently guides the air flowing rearward along the side wall to the rear of the cargo bed and guides the air behind the door. The generated vortex is made as small as possible to reduce the air resistance due to the vortex.

し得るトラックの荷台構造を提供することにある。However, the rear structure of the van-type truck described above has a drawback that the storage capacity of the carrier is reduced because the guide panel is attached to the rear wall. In other words, the total length of the current truck is limited by law, and providing a guide panel on the rear wall within this limit means reducing the overall length of the carrier itself, which reduces the storage capacity of the carrier. There is. Particularly, in the conventional double door, a so-called lock bar is provided outside the door, and the total length of the truck is defined by the distance from the front end of the truck to the lock bar. For this reason, when the guide panel projects rearward of the loading platform beyond the lock bar, it is necessary to shift the mounting position of the double door itself forward by an amount by which the guide panel projects, and mount the door.
There is also a problem that the total length of both side walls and the roof of the carrier must be changed. SUMMARY OF THE INVENTION An object of the present invention is to provide a truck bed structure capable of reducing air resistance during traveling of a truck without reducing the accommodation capacity of the truck.

で、同様に荷台10の収容容積を減少させない。[0013] In the truck bed structure thus configured, an inclined surface or a curved surface facing inward toward the rear of the bed is formed at the rear of the bed 10, so that when the truck runs, both side walls of the bed 10 are formed. The air flowing backward along the roof 11 and the roof 12 is gently guided at the rear of the rear of the door 13 as shown by the dashed-dotted arrow A in FIG. Air resistance can be reduced. In this case, the inclined surfaces formed on both side walls 11 are columns 1 on which stays 11d are not provided.
Since the rear portion of the outer wall 11c behind 1a is formed closer to the inner wall 11b toward the rear end, the storage capacity of the carrier 10 is not reduced. Further, even on the inclined surface of the roof 12, the rear part of the outer wall 12c is formed to be curved so as to approach the inner wall 12b toward the rear end, so that the storage capacity of the load carrier 10 is not similarly reduced.

For this reason, the accommodation volume is increased by the amount of deviation as compared with a conventional bed using a double door provided with a lock bar outside the door. Also, both side walls 11 are columns 11a.
And a plurality of stays 11d, the plurality of stays 11d are protruded behind the column 11a, and the double-sided door 13 is pivotally supported at the tip of the plurality of stays 11d. Alternatively, it can be formed on an inclined surface. Further, since the side outer surface of the door 13 is formed to be curved so as to be continuous with the inclined surface formed at the rear of the side walls 11, the air flowing from the rear ends of the side walls 11 to the rear of the door 13 is
As shown by arrow A in FIG. 1, the door 1 is guided rearward along the curved surface 13 a of the double door 13 from the end, so that the door 1
The vortex generated behind 3 can be further reduced to further reduce the air resistance.

容積をその偏倚量だけ増加させることができる。As described above, according to the present invention, since the rear portions of the outer walls of both side walls of the carrier are inclined or curved so as to approach the inner wall toward the rear end, the storage capacity of the carrier is reduced. It is possible to form an inclined surface or a curved surface facing inward toward the rear at the rear portion of the side walls without the need. The inclined surface or the curved surface guides the air flowing rearward along the side walls of the truck gently to the rear of the double door when the truck runs, so that the air resistance during the running of the truck can be reduced. In this case, since the outer walls of both side walls except the hinge portion are brought closer to the inner wall, the strength for pivotally supporting the double door is not reduced. In addition, if the upper surface of the rear part of the roof is formed so as to be inclined or curved so that the height becomes lower toward the rear end, the air flowing backward along the roof is gently guided to the rear of the double door, so that the air is further increased. Resistance can be reduced, and if the side outer surface of the door is inclined or curved so as to be continuous with the inclined surface or curved surface of the rear portion of both side walls, air flowing from the rear ends of both side walls can be curved. Gently guides the rear side of the door, the air resistance can be further reduced. On the other hand, the overall length of the truck is defined by the distance from the front end of the truck to the outer surface of the double door, so if a double door with a lock mechanism inside the outer surface is used, the outer surface of the double door is set to the specified value. Of the lock bar can increase the accommodation volume by the amount of the deviation as compared with a conventional bed using a double door provided on the outside of the door.
