PROBLEM TO BE SOLVED: To provide a new frame connecting structure, allowing a worker to easily and correctly judge the turning operation for connection to implement efficient connecting work. SOLUTION: In this frame connecting structure, a locking piece 31 of a connecting member 3 connected to a butt end of a horizontal frame 2 is inserted in a dovetail groove 11 of a side of a vertical frame 1, and turned and locked, thereby connecting the vertical frame 1 and the horizontal frame 2 to each other. The locking piece 31 is provided with a rotation stop projecting part 311 projected on the horizontal frame 2 side, and when the locking piece 31 is turned and locked in the dovetail groove 11 of the vertical frame 1, the rotation stop projecting part 311 comes into contact with the dovetail groove 11.
