Continuously variable transmission belt inspection method and inspection device thereof

A Continuously Variable Transmission (CVT) belt inspection device comprising:

• a detection means for detecting an intermittent flaw along a circumferential direction of a metal belt inner circumference surface situated in an innermost circumference layer of a CVT belt, which incorporates trial use in a testing device of an actual vehicle or an actual vehicle equivalent;
• a determination means for determining whether or not a repeating period of a flaw corresponds to a predetermined reference period when said intermittent flaw is detected by said detection means, wherein a case of corresponding determines the cause of a flaw as being an object attributable to an irregular-shaped area formed on a metal element saddle part which constitutes said CVT belt, and wherein a case of not corresponding determines the cause of a flaw as being a substance attributable to an innocuous impurity which penetrated into said CVT belt;
• and
• a display means for displaying a determination result of said determination means.
