In a housing (1) having an inlet (3) and an outlet (4), a rotor (20) has been mounted rotatably. The rotor has rows of bristles (25) in axially extending, circularly spaced apart rows. The axes of the inlet radially extending inlet (3) and of the outlet (4) are angularly related relative to each other only so far that at least two rows of bristles fit against the inside lying peripheral wall (2) and thus guarantee a good seal of the spreading device. The shaft (22) of the rotor (20) is coupled with the drive shaft (31) of an electromotor (30) by means of a coupling (32) which in the direction of rotational torque is resilient or elastic, in order to keep the starting load of the motor (30) low. The electromotor (30) is entirely capsulated and is surrounded by a housing (33) which is connected with the housing (1). At the point of connection, a sleeve (34) provides a hermetic seal. As a result of the relatively slight deflection of the spreading material between the inlet (3) and the outlet (4), the losses due to friction in the rotor (20) are relatively small.
