PROBLEM TO BE SOLVED: To provide a frame connecting structure capable of improving perpendicularity and perpendicular strength in perpendicular connection between frames. SOLUTION: In the frame connecting structure, a side surface of one frame 1 and an edge surface of the other frame 2 are interconnected via a connecting member 3. The connecting member 3 has two perpendicular projecting sections 31 and 32 that are inserted into dovetail grooves 11 and 21 of one frame 1 and the other frame 2, respectively, and are fixed by fastening screws 4a, 4b, 5a and 5b. The other frame 2 has a tapered surface section 212 where screw tips 51a and 51b contact on a depth wall surface 211 of the dovetail groove 21 in fastening the fastening screws 5 and the other frame 2 is pulled to one frame 1 following turning thereof.
