Further, the intensity of the current flowing through the exciting coil(7) controls a braking force. Then, by the braking force, a heat due to a friction among the driving member(3), the magnetic particles(15) and the driven body(10) is generated. A blast panel(16) generated the air fluid(23) integrally connected with the driving member(3). The cooling effect of the driven body(10) is elevated by exposing many large and small exposing protrusions(18,19,20,21) for cooling formed on the diaphragm panels(9,17) into the air fluid(23).
