A device which drives accessories such as an alternator or a cooling water pump utilizing output of an automobile engine, comprises an input shaft installed to an output shaft of the engine, a nonstage transmission with differential planetary mechanism of frictional transmission type installed between the shaft and a pulley connected to the accessory, a frictional transmission oil in an annular space enclosing the nonstage transmission, and forced cooling fans installed on both end plates of the pulley. Each forced cooling fan acts so that heat stored in the frictional transmission oil during the operation is effectively dissipated through the end plate to the outside. As a result, the transmission efficiency of the drive device is maintained at a high level.
