description PROBLEM TO BE SOLVED: To provide a duct connection structure easy of connection work and free of bad connection. SOLUTION: At a connection portion between a duct connection port 2 opened in air conditioning equipment and an opening portion 3a of a cylindrical duct 3, the opening portion 3a of the cylindrical duct 3 is opposed to the duct connection port of the air conditioning equipment 1. A flange 3f provided on the outer periphery of the opening portion 3a is thrust and supported in the direction of the air conditioning equipment 1 by three thrust members 4, 5, 6 arranged at 90° intervals in a lower half peripheral region including an opposite position in a diameter direction R of the outer periphery of the duct connection port 2 and a locking member 7 arranged in a remaining upper half peripheral region excluding the lower half peripheral region and elastically deformable to the direction of the air conditioning equipment 1 and to the outside of the flange 3f.
