Patent abstract
An electric tool causes a drive mechanism to drive a tip tool to thereby cause the tip tool to perform predetermined work, and the drive mechanism is provided with a driving gear and a driven gear which meshes with the driving gear. The electric tool is configured in such a manner that an axial force or a radial force generated by the meshing between the driving gear and the driven gear is measured to detect the state of torque acting on the tip tool, and drive control of the drive mechanism is performed according to the detected state of torque.
