PROBLEM TO BE SOLVED: To secure coupling strength between a piston and a driver blade in a driving machine, and to reduce a manufacturing cost. SOLUTION: The driving machine is equipped with: a cylindrical cylinder; the piston reciprocating in the cylinder; and the driver blade coupled with the piston. The driver blade is formed like a plate. The piston has a groove formed for inserting the driver blade. The piston and the driver blade are coupled through tightening with a nut.
