PROBLEM TO BE SOLVED: To provide a frame structure of a harvesting machine having high strength supporting a load, capable of being manufactured simply and preventing its damage, and facilitating its cleaning. SOLUTION: This frame structure of the harvesting machine C is constituted such that left and right truck frames 20, 20 are connected with a machine body frame 10 through a pipelike connection frame 40. The connection frame 40 is constituted by a pipe whose intermediate part 40a between right and left sides is formed and curved like a crest when viewed in the forward and backward directions of a machine body, whose both right and left end parts 40b are horizontally formed, and whose cross sectional shape is circular. An upper side part of a crest-shaped curved frame part 40A is connected with the machine body frame while it enters the machine body frame from below, and horizontal frame parts 40B, 40B at both right and left ends are connected with upper faces of the truck frames 20, 20 while they are in contact with the upper faces thereof.
