Claim Text:
1. A drive device comprising: a motor having a rotor that is rotatably disposed relative to a stator; a cover having a one-end-closed cylinder shape and positioned on one axial end side of the motor; a substrate disposed inside of the cover perpendicular to a motor shaft having electronic components implemented on the substrate to control an electric current supplied to the motor; a connector positioned on a motor side of the substrate with an opening that is connectable to an external terminal, the opening of the connector facing outward relative to the motor shaft; and a heat sink having a frame end part and a heat receiving part formed in one body to absorb heat from the electronic components implemented on the substrate, the frame end part covering a substrate side of the stator and the rotor, and the heat receiving part positioned radial inside of the connector, relative to the motor shaft, when viewed at a direction through the motor shaft, and rising from the frame end part toward the substrate, when viewed at an other direction perpendicular to the motor shaft.
