Abstract
An electric oscillating tool has an electric motor having an output shaft, an eccentric shaft that is connected to one end region of the output shaft, and a weight that is connected to the other end region of the output shaft. A blade as a tool accessory is driven to reciprocally rotate around a spindle by reciprocating motion of the eccentric shaft in a transverse direction of the electric oscillating tool. The weight is driven to cancel out the inertial force of the eccentric shaft, so that the output shaft is stably rotated.
