PROBLEM TO BE SOLVED: To provide a fastener driving machine requiring no exclusive part and mechanism for returning a driver driven by a flywheel to an initial position. SOLUTION: The fastener driving machine is provided with a driver operation part including the driver 12 linearly operated and hits the fastener by driving the driving operation part by rotation energy stored in the flywheel 24 rotated by a driving source. After the flywheel 24 is rotated/driven to the first predetermined number of revolution, the flywheel 24 is friction-engaged with the driver operation part and the driver 12 is driven to hit the fastener. After the flywheel 24 is reversely rotated to the second predetermined number of revolution, the driver 12 after hitting the fastener is returned/operated to the initial position by friction-engaging the flywheel 24 with the driver driving part side.
