Abstract
There is provided a spray gun comprising: a gun main body; and a trigger having a first locking portion and a second locking portion, the first locking portion locked at one end of a shaft portion provided on the gun main body, the second locking portion locked at the other end of the shaft portion, the trigger operable to rotate about the shaft portion, wherein the shaft portion comprises: a first retaining shaft disposed in a mounting hole formed in the gun main body and locked rotatably on the first locking portion of the trigger; and an elastic member disposed in the mounting hole to bias the first retaining shaft in a direction in which the first retaining shaft exits from the mounting hole.

A spray gun comprising:
- a gun main body;
- a through hole penetrating the gun main body;
- a shaft assembly in the through hole, the shaft assembly including:
- a first retaining shaft,
- a second retaining shaft, and
- a single elastic member between the first retaining shaft and the second retaining shaft biasing both the first retaining shaft and the second retaining shaft in a direction in which the first retaining shaft and the second retaining shaft move away from each other and in which the first retaining shaft and the second retaining shaft exit from the through hole;
- a trigger having a first locking portion rotatably locked onto the first retaining shaft, and a second locking portion rotatably locked on the second retaining shaft, wherein the trigger is operable to rotate about the first and second retaining shafts.
