1. A nailing machine, comprising:
a nail supply unit which supplies a nail to a driving position; and
a driving unit which drives the nail supplied to the driving position, wherein
the driving unit has:
a cylinder unit which has a cylinder having a cylinder cap formed of an elastic member and a piston which slides in the cylinder;
a driving rod which is consecutively provided on the piston and slidably penetrates the cylinder cap,
a driving spring which biases the piston in a driving direction; and
a moving unit which moves the piston in a counter-driving direction against a biasing force of the driving spring;
the moving unit has:
an electric motor; and
power converting means which converts a rotary motion of the electric motor to a linear motion in the counter-driving direction of the piston; and
the power converting means has a sector gear set in rotary motion and driven by the electric motor and a rack gear meshed with the sector gear and is mounted on the piston and is set such that, when the piston moves to a predetermined position in the counter-driving direction, meshing between the sector gear and the rack gear is disengaged to release the driving spring, and the drive spring is released due to only disengagement of meshing between the sector gear and the rack gear, thereby moving the piston to drive the nail.
