Abstract

In the belt according to the present invention, the whole or a part of a belt body is formed from a thermoplastic resin composition (C) comprising a thermoplastic resin (A) and a modified ethylene copolymer (B) dispersed and contained therein. The modified ethylene copolymer (B) is preferably a copolymer, modified with an unsaturated carboxylic acid or a derivative thereof, of ethylene with at least one monomer component selected from (i) olefin components except for ethylene, (ii) diene components and (iii) ester components having an ethylenically unsaturated group. The belt according to the present invention hardly causes abrasion, damage, cracks, breakage and the like on the belt body and is remarkably excellent in durability, even if the belt is used at a high load for a long time.
