Abstract
An air duster structure that is configured to jet compressed air out of a nozzle, includes a flow amount adjustment mechanism which is configured to adjust an amount of air jetted out of the nozzle. The flow amount adjustment mechanism includes: a pipe line for circulating air; a valve member disposed inside the pipe line and being movable; and a throttle portion configured to gradually change an area of a flow channel in which air circulates, with a movement of the valve member, to control a flow amount of the air in the pipe line. The throttle portion is structured so as to increase the area of the flow channel at an accelerated rate when the valve member moves in a direction that opens the pipe line.
