Abstract
An air cannon is provided with an air cannon body having a cylindrical body partitioning an air chamber and an end plate provided at the cylindrical body, and compression means that is provided at the air cannon body and reduces a volume of the air chamber. In the air cannon, an ejection port having an inner-side opening end and an outer-side opening end that is larger than the inner-side opening end is formed in the end plate. The air inside the air chamber is ejected as air vortexes from the ejection port by driving the compression means.
