PROBLEM TO BE SOLVED: To provide a nailing machine of high energy efficiency.SOLUTION: A nailing machine 1 includes a housing 2, a plunger 3, a coil 4, a control unit 5, and a battery 6. The plunger 3 is reciprocally accommodated in the housing 2, and a magnet 31 having at least three magnetic poles is arranged in the reciprocal direction. The coil 4 is accommodated in the housing 2, and arranged outwardly in the radial direction of the plunger 3 so as to surround the plunger 3, and has a first coil 41 and a second coil 42 to be wound in the circumferential direction of the plunger 3. The control unit 5 controls power supply to the coil 4. The battery 6 supplies power to the control unit 5. |
