PURPOSE: A mounting structure of a generator pulley is provided to prevent the slipping generated between a belt and a pulley by allowing the pulley to relatively move to a driving shaft. CONSTITUTION: A hub(10) is inserted into a driving shaft(3) of a generator and provided with a projection(12) having a through hole at an external surface. A pulley(20) is provided with a projection(22) having a through hole at an internal surface opposite to the projection(12) of the hub(10). A spring(30) is installed within the pulley(20) and the hub(10). A side end of the spring(30) is inserted into the through hole of the pulley(20) and a side end(32) of the spring(30) is inserted into the through hole of the hub(10). First and second bearings(40,41) are pressed and inserted on upper and lower portions between the pulley(20) and the hub(10). A space(50) is formed between the hub(10) and the pulley(20) so as to transform smoothly the spring(30).
