发明名称 Friction drive belt
摘要 A friction drive belt includes: an adhesion rubber layer having a core wire embedded therein so as to form a helical pattern having a pitch in a lateral direction of the belt; a compression rubber layer provided on a surface of the adhesion rubber layer located on an inner side of the belt, and serving as a portion that is to contact pulleys, and a backing rubber layer provided on a surface of the adhesion rubber layer located on an outer side of the belt, and serving as a back portion of the belt. A ratio of tensile stress at 10% elongation of a rubber composition forming the adhesion rubber layer to that of a rubber composition forming the backing rubber layer is 1.77 or more, as measured in a longitudinal direction of the belt at an ambient temperature of 25° C. according to JIS K 6251.
