An aerosol spray gun used selectively in two spraying modes of small pattern and large pattern and is provided which can be comprised of simple components. Aerosol spray gun 1 includes a throttle valve mechanism 35, an air duct 43, and a coupling link 45. The throttle valve mechanism 35 is provided in an internal air duct 23 for supplying pressurized air to a patterning air outlet 21 which shapes a paint spraying stream jetted out from the aerosol spray gun 1, and it has a movable valve element 39 to which a compressed spring 41 applies force to open the valve. The air duct 43 created at the tip of the movable valve element 39 supplies a small volume of air from the internal air duct 23 to the patterning air outlet 21 while the movable valve element 39 seats on a value seat 37. The coupling link 45, coupling the movable valve element 39 to the trigger 7, is provided with an elongated hole 47 to disconnect the trigger 7 from the movable valve element 39 without cooperative relation between them from an initial stage where an operator begins to squeeze the trigger 7 to an intermediate stage before the operator fully squeezes the trigger.
