To provide a cargo receiving platform lifting device allowing a cargo receiving platform and cargoes to be equally distributed and carried by two arm plates even when the cargoes are mounted on the cargo receiving platform.SOLUTION: A cargo receiving platform lifting device is applied to lift down and up between the ground and a cargo platform. A parallel linkage mechanism 10 includes upper arms 21, lower arms 23, and lifting drive devices 25. The upper arms 21 include a pair of arm plates 35 disposed on the tip ends thereof to be located opposed to each other in the width direction, and boss portions 28 connected to the arm plates 35. The boss portions 28 are movably fitted to shafts connecting the upper arms 21 to a cargo receiving platform, and integrally include a pair of extending portions extending toward the base portions of the pair of arm plates 35. The extending portions are welded respectively to the pair of arm plates 35.SELECTED DRAWING: Figure 2
