Abstract (en)

[origin: EP2674260A1] An electric tool of the present invention includes a transmission for switching a reduction ratio between a motor as a rotational power source and an output unit rotatably driven by the motor. The electric tool further includes a driving state detecting means detecting at least two driving states, of driving states that vary in response to a magnitude of a load when the output unit is driven, and a controlling means making the transmission switch the reduction ratio when the at least two driving states detected by the driving state detecting means satisfy predetermined conditions preset for the respective driving states.
