PURPOSE:To prevent wear with a higher transmission efficiency by rpoviding either of the surface and the back of a flat belt with at least two of characteristics of a high friction coefficient, a wear resistance and oil absorptivity. CONSTITUTION:The surface or the back of a flat belt 1 is formed by combining at least two of a material 12 with characteristic of a high friction coefficient, a material 13 with characteristic of a wear resistance and a material 14 with characteristic of oil absorptivity. |
