Abstract
Official abstract text for this publication.
A flat belt (B) includes a cord retaining layer ( 11 ) in which a cord ( 14 ) extending in a belt length direction and arranged helically at a certain pitch in a belt width direction is embedded, and an inner rubber layer ( 12 ) provided on a belt inner side of the cord retaining layer ( 11 ) and serving as a pulley contracting portion. The cord retaining layer ( 11 ) is made of a rubber composition containing short fibers ( 15 ) which are mixed in a rubber component in an amount of 1 to 20 parts by mass relative to 100 parts by mass of the rubber component, and are dispersed to be oriented in the belt width direction. The inner rubber layer ( 12 ) is made of a rubber composition not containing short fibers ( 15 ).
