Abstract
An electric working machine may include an output shaft, a rotary blade attached to the output shaft, an output pulley fixed to the output shaft, an input shaft, an input pulley fixed to the input shaft, a transmission belt wrapped around the input pulley and the output pulley, an electric motor including a motor shaft and configured to rotate the motor shaft, a speed reducer configured to reduce a speed of rotation of the motor shaft and transmit the rotation to the input shaft, and a housing that houses the electric motor and the speed reducer, and rotatably supports the input shaft and the output shaft. A rotation axis of the motor shaft may be inclined with respect to a direction which is along a rotation axis of the output shaft.

An electric working machine comprising:
- an output shaft;
- a rotary blade attached to the output shaft;
- an output pulley fixed to the output shaft;
- an input shaft;
- an input pulley fixed to the input shaft;
- a transmission belt wrapped around the input pulley and the output pulley;
- an electric motor comprising a motor shaft and configured to rotate the motor shaft;
- a speed reducer configured to reduce a speed of rotation of the motor shaft and transmit the rotation to the input shaft;
- and
- a housing that houses the electric motor and the speed reducer, and rotatably supports the input shaft and the output shaft,
- wherein a rotation axis of the motor shaft is inclined with respect to a direction which is along a rotation axis of the output shaft, and
- when the electric working machine is placed on a placement surface, the rotation axis of the output shaft is arranged along a left-right direction in a vicinity of a front end of the housing, and in a side view of the electric working machine, the rotation axis of the motor shaft is inclined at an angle within a range from −45° to 45° with respect to an up-down direction.
