PROBLEM TO BE SOLVED: To provide an apparatus of compact size and expand its versatility by integrating a drive unit and a control unit without being influenced by noise. SOLUTION: In this internally-mounted structure of a retarder controller of an auxiliary braking system provided with an electromagnetic retarder body with an exciter built in, its drive unit, and a control unit of generating control signals, a case 31 having a rising stage in the center of the inner bottom thereof is formed, and a power rectifying element 25 is disposed in the center. The drive unit of a substrate 34 surrounded by a long tall part attached with the side of the rising platform 32 of the case 31 and the control unit disposed with a substrate 35 taking a space from the substrate 34 are stored in the case 31. Both the substrates 34, 35 are electrically connected to each other, and a power system and its control system in the substrate 34 are separated. Lead wires to the outside of the case are drawn out respectively from a surface facing the side surface of the case 31 with the power system and the control system separated.
