摘要： An electric power steering device which has, on the outer surface of its gear box, the circuit modules of a control device such as a power module, a frame module, and a control module, and which is easily mountable on a vehicle and less affected by heating. The upper half of the gear box (11) is formed in a rectangular parallelepiped box (11b) in which a reduction gear mechanism is assembled. The first flat face (11b1) of the gear box (11) on the outside of the axis of the center shaft of an electric motor (12) as viewed from a worm gear meshing point is formed as a mounting face for the power module (PM), and the second flat face (11b2) of the gear box crossing the first flat face is formed as a mounting face for circuit parts forming the frame module (FM) and the control module (CM).
