To provide a motor-driven nailing machine having high energy efficiency by low reaction, while realizing miniaturization and weight-reduction.
This motor-driven nailing machine 1 is provided with a housing 2, a motor 8 incorporated into the housing 2, a flywheel 9 to be rotated and driven by the motor 8, a driving block 18 having a blade 18B to drive a nail by rotational force of the flywheel 9, and a clutch mechanism capable of selectively transmitting the rotational force of the flywheel 9 to the driving block 18. In the nailing machine 1, torque for accelerating the driving block 18 is set to 15 to 35N-m. It is desirable that the torque for accelerating the driving block 18 is 21 to 35N-m. Further preferably, the torque should be set to 27 to 35N-m.
