The retarding device includes brake means (12, 17) arranged to be in close relation with the transmission and for actuating a retarding force on a transmission member (2), the brake means being arranged to automatically put a retarding force on said transmission member when the speed of rotation or the torque of rotation of said transmission member falls below a predetermined value.
