A an electric machine tool having a body to which a work tool is attached, a motor, and a battery. The body has a motor receiving chamber, a battery receiving chamber opening through an outer surface of the body, and a communication path through which the battery receiving chamber is in communication with the motor receiving chamber. A first air inlet opening is formed between the inner edge of an opening of the battery receiving chamber and the outer periphery of the battery disposed in the battery receiving chamber. Further, an inflow port of the communication path opens to an inner side surface of the battery receiving chamber and an air filter is fitted over the inflow port.

Electric machine tool

To reduce fatigue in the arm of an operator of a blow operation device driven by an electric motor and to realize a blow operation of blowing and gathering generated compressed air from both the right and left with a small operational burden. A blow operation device includes a backpack type frame, a battery attached to the frame, a blower body having an electric motor to which power is fed from the battery and having an axial fan driven by the electric motor, and a blower tube connected to a blow side of the blower body, the frame including a back contact surface, and the blower body being attached to the frame such that axial directions of the electric motor and the axial fan are along the back contact surface.
