<p>PURPOSE:To transmit a stable moving force by making a non-metallic cushioning substance intervene in an operation system including a driving source. CONSTITUTION:A main gear 10 is inserted in a boss 35 provided on the leading edge of a driving shaft 8 and the non-metallic cushioning substance, that is, a felt 33a, is provided on the contact part with coil springs 37 which hold the main gear 10 between them. Therefore, in the main gear 10 which transmits a rotating force to a cylindrical mechanism part, a part where it touches with metal becomes smaller and the occurrence of dust can be reduced, then the stable moving force can be transmitted.</p> |
