It is a spray-gun air cap positioning device, wherein on the inner surface of an air cap (3), facing the front end face (11) of a spray gun body (1) to which the air cap (3) is to be attached, there are provided two pins A on a circle concentric with the air cap (3); on the front end face of the gun body (1), there is provided a pin B on a circle generally concentric with the circle on which the pins A are provided; the pins A and pin B are of such lengths that when the air cap (3) is attached to the gun body (1), the pins A and B will abut on each other to limit the air cap (3) from being further turned; and each of the pins A and B is provided in such a position that the air cap (3) can be turned through an angle of 90 deg. defined between a position where any one of the pins A1 (or A2) at the air cap (3) is limited by the pin B at the gun body (1) from being further turned and a position where the other pin A2 (or A1) is limited by the pin B from being further turned.
