Patent ID: 8567521

Claim:
A power tool comprising: a case; a motor installed within the case, the motor comprising a motor housing and a rotor including a motor shaft; a gear train comprising a gear train housing and a speed reduction mechanism installed within the gear train housing and connected to the motor shaft; and a switch installed within the case; wherein the motor housing and the gear train housing are integrally formed as a common housing having a single piece monolithic construction and fixed relative to the case, the motor comprising a first axial end adjacent to the gear train and a second axial end remote from the first end and the gear train, the first axial end located axially between the gear train and the second axial end, the motor housing defining a radial opening at a portion adjacent to the gear train and away from the second axial end of the motor, the radial opening being adjacent to the switch, which is closer to the first axial end of the motor than to the second axial end of the motor; wherein the motor further comprises one of a brush card and a circuit board installed within the common housing at the first axial end and adjacent to the switch; and wherein a pair of power leads extend through the radial opening and is connected to the switch and the one of a brush card and a circuit board for providing power to the motor.
