PURPOSE: A mixing tip coupling structure of an impression material cartridge is provided to drastically improve convenience of the use by easily combining the mixing tip with the impression material cartridge and to completely prevent the leakage of the impression material due to the annealing of the mixing tip. CONSTITUTION: A rotation protrusion(16a) has a diagonal symmetry when a wing portion(16) for the bond is combined with a rotary joint groove(7a)(8a) of the mixing tip coupling end(7)(8) of the impression material cartridge(1). A semi-cylindrical guide pin(16b) guiding the combining direction of the mixing tip is downwardly protruded on the lower part of the rotation protrusion. A guide plate(9) for bonding the mixing tip is projected on the upper part of an upper coupling plate(5) formed in the impression material cartridge.
