ABSTRACT:
A defect inspection device for metal ring end faces of a Continuously Variable Transmission (CVT) V-belt which enables automated inspection of end face defects in the metal rings along with acquiring improved efficiency, superb precision and reproducibility. When end face defects in the metal ring are inspected by an inspection section, this task is accomplished by an angle modification portion which performs an angle modification operation continuously in a predetermined range (θ1˜θ5) relative to an inspectable surface for at least a first light guiding path and a second light guiding path included in the defect inspection section. Because this automated modification operation corresponds to processing by manual visual inspection and applies a common practice detection method used in labor-intensive visual inspections by changing the viewing angle to detect defects, such as a gloss mark, the object of the present invention can be achieved.
