PROBLEM TO BE SOLVED: To provide a combination type carrying vehicle capable of lifting/lowering a deck with a simple structure, and ensuring the strength of a coupling portion between the deck and the carrying vehicle, even if a plurality of the carrying vehicle are coupled by the decks. SOLUTION: According to the combination type carrying vehicle 1, an outer wheel 33 is engaged with a guiding groove 40a of a guiding rail 40, thereby guiding lifting/lowering of the deck 10. The outer wheel 33 is engaged with the guiding groove 40a of the guiding rail 40, thereby coupling the deck 10 and the carrying vehicle 20. Since the lifting/lowering of the deck 10 is guided by using a structure coupling the deck 10 and the carrying vehicle 20, even if the deck 10 couples two carrying vehicles 20, the deck 10 can be lifted/lowered by a simple structure. On the other hand, the deck 10 and the carrying vehicle 20 are coupled by using a structure guiding the lifting/lowering of the deck 10, so that the strength of the coupling portion can be ensured.
