PROBLEM TO BE SOLVED: To provide a cargo receiving base lifting device having a cargo receiving base capable of improving durability, and capable of restraining a weight increase.SOLUTION: The present invention aims at a cargo receiving base lifting device having a cargo receiving base supported by an installation member of both left-right end parts and rotatable between a horizontal attitude and a standing attitude with the installation member as the axial center. The cargo receiving base comprises a metallic plate material 31 and a peripheral projection mold part along an edge part in its reverse surface part. Among the projection mold part, a first projection mold part 304 sandwiched by the installation part comprises a first wall body 3041 and a second wall body 3042 erected in the reverse surface part and with the lateral direction as the lengthwise direction and an opening part S1 sandwiched by the first wall body 3041 and the second wall body 3042. A frame mold body is continuously provided in the reverse surface part by at least one of the first wall body 3041 or the second wall body 3042 and a residual part different from the first projection mold part 304 among the projection mold part, and the one is larger in a thickness than any one of the wall body among a residual part of the projection mold part.SELECTED DRAWING: Figure 2 |
