<p>In order to improve durability by improving the strength of the rubber itself while increasing the peeling strength with respect to core wire, canvass, or short fibers, a toothed belt (10) is equipped with: a belt main body (13), which is integrally formed by means of tooth rubber (11) provided on one surface and back rubber (12) provided on the other surface; and core wire (14), which is wound in a spiral shape and embedded extending in the lengthwise direction of the belt, in the boundary portion between the tooth rubber (11) and the back rubber (12). A tooth fabric (20) that covers the tooth rubber (11) is bonded to the surface of the tooth rubber (11), that is, to the one surface of the belt main body (13). The tooth rubber (11) is obtained by vulcanization molding of a rubber composition that includes HNBR or other rubber, resorcinol, a melamine compound, silica, and the like.</p> |
