A device is described for driving accessories such as an alternator, a cooling water pump, an air-conditioning compressor or the like, utilizing power taken from an output shaft of an engine, the device comprising: an input shaft pivotally supported to a stationary element and receiving output from the output shaft and rotated at the rotational speed corresponding to that of the output shaft; a transmission output member rotatably supported on the input shaft for transmitting the power to the accessory; a planetary cone which can rotate on the input shaft in the revolution around the axial center of the input shaft and in the rotation around the axial center inclined with respect to the axial center of the input shaft. The planetary cone has a first part of nearly conical shape, and a second part of nearly cylindrical shape leading to a bottom surface of the first part, and first, second and third frictional transmission surfaces being formed on the conical surface of the first part, the bottom periphery of the first part and the circumferential surface of the second part, respectively; and an input transmission member installed rotatable with the input shaft and engaged at outer periphery of frictional engagement with the second frictional transmission surface of the planetary cone.
