Abstract
Official abstract text for this publication.
A toothed belt has therein a core wire ( 3 ) including a core thread ( 1 ) made of aramid fiber and a filament thread ( 2 ) made of nylon fiber, and has belt tooth portions ( 4 ) and belt groove portions ( 5 ) alternately formed therealong. The core wire ( 3 ), the belt tooth portions ( 4 ), and the belt groove portions ( 5 ) are integrated with one another by a rubber material ( 7 ). It should be noted herein that the core thread ( 1 ) and the filament thread ( 2 ) are integrally twined around each other so that the filament thread ( 2 ) is formed in the shape of a plurality of loops around the core thread ( 1 ). The filament thread ( 2 ) in the shape of the loops enters tooth root portions ( 9 ) of the belt tooth portions ( 4 ) to be arranged therein. As a result, the tooth root portions ( 9 ) are strengthened.
