PROBLEM TO BE SOLVED: To provide a conveying device capable of preventing a frame from being floated up when a vehicle is lifted up. SOLUTION: Since the conveying device 1 of the present invention is constituted such that an expansion/contraction member 7 interposed between an auxiliary wheel 6 and an arm member 4 is expanded to raise the arm member 4, when load of the vehicle 100 is applied to the arm member 4 projected from one end side in a traveling direction of the frame 2, the expansion/contraction member 7 supports the arm member 4 relative to the ground and can prevent the other end side in the traveling direction of the frame 2 from being floated up.
