    摘要： An electric fastener driver having a compact size and simple construction. A driver segment provided with a rack is movably disposed in a housing. A flywheel is driven by a motor. A drive shaft is concentric with and integral with the flywheel. A coil spring is fixed to the drive shaft. A driven rotor is coaxial with the drive shaft and has one end portion serving as a spring seat portion positioned within the coil spring. A pinion is disposed at the driven rotor and is meshedly engaged with the rack. An urging section is disposed within the driven rotor. A ball is movably disposed in a through-hole formed in the driven rotor for urging an end portion of the coil spring by the urging section. A solenoid controls a protruding amount of the ball from the surface of the driven rotor.

    摘要： A pulse torque generator utilizing a magnetic coupling, and an electric power tool provided with the pulse torque generator. The pulse torque generator includes an input shaft extending in its axial direction and having a hollow section providing a hollow space, and an output shaft rotatably provided in the hollow space. A magnetic fluid is encapsulated in a hollow space between the input shaft and output shaft. A magnetic field generating unit is disposed, and magnetic segments are provided in the input shaft. A magnetic fluid provides a magnetic fluid bridge bridging between the input shaft and the output shaft each time the magnetic segment is brought into confrontation with the magnetic field generating unit.
