PROBLEM TO BE SOLVED: To provide a coupling structure of a frame of an air-conditioner having a good strength stably and offering a wide versatility. SOLUTION: The horizontal surface part 2a and a first vertical surface part 2b of a first horizontal plate are laid on the horizontal surface part 5c and a first vertical surface part 5a of a coupling metal piece and coupled together by bolts 8, and the horizontal surface part 3a and a first vertical surface part 3b of a second horizontal plate are laid on the horizontal surface part 5c and a second vertical surface part 5b of the coupling metal piece and coupled together by bolts 9, and the first and second vertical surface parts 5a and 5b of the coupling metal piece are laid on the first and second vertical surface parts 1a and 1b of each vertical plate and coupled together by bolts 7. When the bolts 7, 8, 9 are fastened with nuts, the bolt-nut fastening force is made uniform using a torque wrench approximately, so that the coupling structure of the frame of the air-conditioner can provide a specified strength easily, and a wide versatility is obtained.
