<P>PROBLEM TO BE SOLVED: To provide an electric power steering device that has a control device arranged between an electric motor and a decelerator and achieves cost reduction, improvement in joining reliability, and also, improvement in device assembly workability by mounting a circuit substrate inside the control device and a heat sink fixed to the decelerator and integrating them with the electric motor. <P>SOLUTION: The electric power steering device is configured as follows. A control device 20 and an electric motor 1 are separately assembled. When a press-fit terminal 10p formed to a connection terminal 10 is extended and a circuit substrate 22, bonded to a heat sink 21 inside the control device 20, and the electric motor 1 are incorporated with each other, an armature winding 9 of the electric motor 1 receives press-in force by a pressure receiving part 21a of the heat sink and is electrically connected with the circuit substrate when the press-fit terminal 10p is pressed into a through-hole 28b of the circuit substrate 22. <P>COPYRIGHT: (C)2010,JPO&INPIT |
