<p>An auxiliary device driving unit driven by an engine comprises an input member (6) fixed to a crank shaft (2) of the engine and provided with a disc-like portion (6a) and a cylindrical portion (6b), an output member (7) placed opposing the disc-like portion in a freely rotatable manner, the output member (7) having the same axial center as the cylindrical portion of the input member, a plurality of planet cone members (8) in a conical shape which are supported by the outer peripheries of the input and output members (6,7) through partial contact, a speed change ring (10) which is in contact with the cone generatrix of said planet cone members (8) and is movable along the same axial center line as the input member (6), a speed change shaft (19) having a feeding means for controlling movement of the speed change ring (10) in the axial direction, a motor (20) for rotating the speed change shaft (19), an electric circuit for controlling the motor (20), a driven member (13) which is coupled to the output member (7) through a ball cam (16) and is rotatable on said cylindrical portion (6b) of input member (6) and a crank pulley (3) fixedly supported by the driven member (13).</p> |
