ABSTRACT:
The apparatus comprises a planetary gear device and a magnetic particle type electromagnet clutch. The planetary gear device has a gear element connected to an input member, another gear element connected to an output member and a remaining other gear element. The electromagnetic clutch has a fixed member provided with a exciting coil and a rotary member adapted to be fixed to the fixed member by controlling intensity of electric current in the exciting coil. The rotary member is connected to the remaining other gear element.
Further, the electromagnetic clutch comprises a fixed outer member having side wails opposite to each other and a circumferential wail, a rotary inner member provided inside of the outer member rotatably relative to the outer member, electromagnetic powders interposed between the outer and inner members and magnetized by excitation of the exciting coil to form a linkage for connecting the outer and inner members, a ring-shaped electromagnetic powder chamber provided along at least one of the inner surface of the side wall of the outer member and a side surface of the inner member and opened radially outwardly, and a plurality of partition wails circumferentially dividing the electromagnetic powder chamber into a plurality of small chambers.
