Tire deterioration situation measuring instrument, its holding jig and tire deterioration situation measuring device

摘要

Problem to be solved: to provide a tire deterioration situation measuring instrument capable of imaging an image of a crack in the groove portion of the tire and the side surface of the tire, as well as the depth of the groove formed on the ground plane of the tire.Solution: the housing 2 provided with the window part 3 disposed in contact or proximity to the ground plane 17 of the tire 16 is provided on the measuring surfaceThe housing 2 is provided at a position relative to the window part 3A distance measuring sensor 9 which slides in a direction crossing the groove part 18 of the tireThe illumination light source 10 slides in the same direction as the distance measuring sensorThe imaging device 11 slides in the same direction as the distance measuring sensor 9, andDistance sensor 9Slide mechanism 10 for sliding light source 10 and imaging device 11Equipped withImage pickup device 11 and light sourceThe tire deterioration situation measuring instrument 1 is characterized in that the tire 16 slides at a position away from the tire 16 beyond the edge 16A of the ground surface 17 of the tire 16.Diagram
