Abstract
An improved speed reduction drive for an electric chain saw is disclosed. The speed reduction drive comprises a first rotatable member directly driven by the drive shaft of the electric motor for rotation therewith. A second rotatable member is connected to the drive sprocket for the cutter chain for rotation in the same direction. At least one endless drive loop drivingly connects the first and second rotatable members for rotation in the same direction, whereby rotational inertia of the electric motor opposes 'kickback' of the chain saw.
