Abstract
A conveyor belt includes an upper cover rubber and a lower cover rubber disposed above and below a core layer; and a protective fiber layer made from high strength fiber disposed at least in a central portion of the upper cover rubber in a belt width direction and extending continuously in a belt longitudinal direction; an elastic modulus E of the protective fiber layer in the belt longitudinal direction being a low elastic modulus Eequal to or less than a predetermined value when a tension in the belt longitudinal direction acting on the conveyor belt is equal to or less than a setting tension Ts, and being a high elastic modulus Ehigher than the low elastic modulus Ewhen a predetermined high tension higher than the setting tension Ts is acting on the conveyor belt.
