Lead terminals of a plurality of motors disposed inside a drive unit casing are lead out through a plurality of elongated through-holes formed in the casing and connected to a plurality of power-supply sheathed wires by connecting terminals. A plurality of elongated concavities is formed adjoining to the corresponding through-holes on the outer surface of the casing. With the connecting terminals connected to the plurality of sheathed wires, the plurality of lead terminals extended from the motor are bent through a nearly right angle at the open ends of the through-holes along the outer surface of the casing and the connecting terminals are forcibly fitted on the side walls of the elongated concavities. Therefore, the electrical connection between the lead terminals extended from the plurality of motors and the plurality of power-supply sheathed wires needs no soldering. The sheathed wires can be very easily connected to the lead terminals of the motors and they can not be easily disconnected from the lead terminals.
