<p>PURPOSE:To allow the wide range of choice of the location, configuration and the like of the transmission part by a method wherein the driving power is transmitted by a cover fixed to a rotary main body. CONSTITUTION:The cover 10 prevents dust, muddy water or the like from entering in a gap between the friction surfaces 3a and 12a of the rotary main body 3 and of an armature 12 or bearings 4. A pulley 10a comprising a transmission part is integrally formed on the outer periphery of said cover 10 which is connected onto the outer periphery of the rotary main body 3 by means of bolts 11. A V-belt, through which the rotation of an engine is transmitted to the cover 10 and the rotary main body 3, is put over the pulley 10.</p> |
