To provide a tire deterioration state measuring unit that can take an image to analyze a generation distribution of cracks in the treads of a tire and in the side surfaces of a tire.SOLUTION: A tire deterioration state measuring unit 1 includes: a housing 2 having a window part 3 in a measurement surface 4, the window part being in contact with a ground surface 17 of the tire 16 or being close to the ground surface; a light source 10 for illumination located in a position of the housing 2 which faces the window part 3, the light source sliding in a direction that crosses the tread part 18 of the tire 16; an imaging device 11, which slides in the same direction as that of the light source 10; and a slide mechanism for sliding the light source 10 and the imaging device 11. The imaging device 11 and the light source 10 slide to a position which is away from the tire 16 across the edge 16a of the grounded surface 17 of the tire 16.SELECTED DRAWING: Figure 1

    【課題】タイヤの溝部内及びタイヤの側面におけるひび割れの発生分布を解析すべく画像を撮像することができるタイヤ劣化状況計測器を提供する。【解決手段】タイヤ16の接地面17に接触又は近接して配される窓部3を計測面4に備えている筐体2と、この筐体2内において窓部3と相対する位置に設けられ、タイヤ16の溝部18を横断する方向にスライドする照明用の光源10と、光源10と同じ方向にスライドする撮像装置11と、光源10及び撮像装置11をスライドさせるスライド機構と、を備え、撮像装置11および光源10は、タイヤ16の接地面17の縁端16aを超えてタイヤ16から離れた位置にスライドすることを特徴とするタイヤ劣化状況計測器1による。【選択図】図1
