PURPOSE:To prevent the occurrence of burning damage of a wire material through which a power source is supplied to a detecting circuit and to enable control of a damping force control system to the safety side, by adding a current control circuit to the power circuit of the rotating angle position detecting circuit of a motor for adjusting a damping force. CONSTITUTION:According to setting of a change-over switch 1, a control circuit body 30 converts a detecting signal, provided from a rotating angle position detecting circuit 6 of a motor 4 for adjusting a damping force, into a comparing inputs to drive each rotor 4 so that it is present at a given damping force position. A power source, necessary to each rotating angle position detecting circuit 6, is supplied to a current control circuit 32 from a power source 31. When a short circuit trouble occurs or an abnormal current is going to flow at a power source line L3 or the interior of the detecting circuit 6, a current detector 33 detects it to cause a current controller 34 to effect current control motion, resulting in suppression of the current of the power source line L3. |
