To provide a tire deterioration state measuring instrument which can capture an image so as to analyze not only the depth of a groove part formed on a grounding surface of a tire but also the generation distribution of a crack in the groove part of the tire and on a lateral surface of the tire.SOLUTION: A tire deterioration state measuring instrument 1 comprises: a housing 2 which has on a measurement surface 4 a window part 3 arranged so as to contact or approximate a grounding surface 17 of a tire 16; a distance measuring sensor 9 which is located at a position opposite to the window part 3 in the housing 2 and slides in a direction crossing a groove part 18 of the tire 16; a light source 10 for illumination which slides in the same direction as the distance measuring sensor 9; an imaging device 11 which slides in the same direction as the distance measuring sensor 9; and a slide mechanism which makes the distance measuring sensor 9, the light source 10 and the imaging device 11 slide. The imaging device 11 and the light source 10 slide to positions apart from the tire 16 across an edge 16a of the grounding surface 17 of the tire 16.SELECTED DRAWING: Figure 1
【課題】タイヤの接地面に形成される溝部の深さのみならず、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測距センサ9と、この測距センサ9と同じ方向にスライドする照明用の光源10と、やはり測距センサ9と同じ方向にスライドする撮像装置11と、測距センサ9、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
