る。Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a back panel of a cab of an automobile. 2. Description of the Related Art Conventionally, as shown in FIG. 4, there is a back panel 2 of a cab 1 of an automobile in which a number of vertical beads 3 are provided. [0005] In the above-mentioned conventional back panel 2, the lower end of the vertical bead 3 is located at a position close to a welding portion 5 between the floor 4 and the back panel 2 as shown in FIG. 5. is there. Therefore, due to a load input to a belt anchor portion or the like fixed to the floor 4, a point A having high rigidity close to the welding portion 5 is locally deformed as a break point. Therefore, the amount of deformation was small, and a peeling load was generated at the welded portion 5. [0004] It is an object of the present invention to provide a cab back panel that prevents local deformation when a load is input to the floor. [0005] In order to achieve the above object, according to the present invention, the floor and the back panel are welded.
And the belt anchor is fixed to the floor.
The back panel has a case with a number of vertical beads.
A plurality of vertical beads near the belt anchor.
Lower end above the welded part of the floor and back panel
The lower end is linked with a horizontal bead,
When a load is input to the belt anchor,
Be sure to increase the amount of deformation of the back panel as a break point.
It is characterized by having. Embodiments of the present invention will be described below with reference to the drawings. In FIG. 1, 1 is a cab, and 2 is a back panel provided with a number of vertical beads. According to the present invention, in the above-mentioned back panel 2,
As shown in FIG. 2, the lower ends of the plurality of vertical beads 3 a near the belt anchor 6 fixed to the floor 4 are largely separated upward from a welding portion 5 (spot welding) between the floor 4 and the back panel 2. It is a structure linked by a horizontal bead 3b. Since the present invention has the structure as described above, the horizontal bead 3b at the lower end of the vertical bead 3a is, as shown in FIG.
It is largely separated at a height H from a point A having high rigidity close to the conventional welding portion 5. Therefore, when a load is input to the belt anchor 6 or the like fixed to the floor 4, the horizontal bead 3b becomes a break point, and a large amount of deformation of the back panel 2 is obtained as shown in FIG. Since the load is input to the welded portion 5 after absorbing the load due to the large deformation of the back panel 2, the load applied to the welded portion 5 is small and the peeling of the welded portion 5 is prevented. be able to. Further, the lower end of the vertical bead 3a is connected to the horizontal bead 3b.
In this case, the break point (boundary point of rigidity) due to the load becomes clear, and the amount of deformation can be adjusted. As described above, according to the present invention, in a conventional back panel having a vertical bead structure, the deformation amount with respect to the load is increased by a simple structure, and the welded portion between the floor and the back panel is separated. Has the advantage of preventing
