Abstract: A working machine may include a working unit including a working mechanism, an electric motor, and a motor housing, a control unit, a base, a rear housing, a front handle, and a rear handle. The base may include a passage. The motor housing may include an inner air inlet and an outer air outlet. The rear housing may include an outer air inlet and an inner air outlet. A cooling air passage may be defined in which air flows from the outer air inlet to the outer air outlet through an inside of the rear housing, the inner air outlet, the inside of the passage, the inner air inlet, and an inside of the motor housing. As viewed along a front-rear direction, the inner air inlet and the inner air outlet may overlap each other.
