PROBLEM TO BE SOLVED: To enable an operator to gasp an abrasion state of a groove part in a rotation body including an undercut part connected to the groove part from an image photographed by an imaging device.SOLUTION: An abrasion inspection device is installed in an elevator comprising: a sheave groove 7 around which a main rope 6 elevating and lowering a car 1 and a balance weight 2 is wound; an undercut part 8 which is provided continuously to the sheave groove 7; and a sheave 5 which moves the main rope 6. The abrasion inspection device includes an imaging device 10 photographing the sheave groove 7 of the sheave 5 and the undercut part 8, and inspects abrasion of the sheave groove 7 of the sheave 5 on the basis of the image photographed by the imaging device 10. A special cut part 9 is formed at a part of a portion in the undercut part 8 of the sheave 5, and the special cut part 9 is a shape whose width dimension of the longitudinal section thereof is decreased according to the approach to the bottom edge.SELECTED DRAWING: Figure 6

    【課題】回転体が溝部に連設されたアンダーカット部を有するものにあって、撮像装置が撮影した画像により回転体の溝部の摩耗状況を把握できるようにする。【解決手段】本発明は、乗りかご1とつり合い重り2を昇降させる主ロープ6が巻回されるシーブ溝7と、このシーブ溝7に連設されるアンダーカット部8とを有し、主ロープ6を移動させるシーブ5を備えたエレベーターに設けられ、シーブ5のシーブ溝7及びアンダーカット部8を撮影する撮像装置10を備え、撮像装置10で撮影された画像に基づいて、シーブ5のシーブ溝7の摩耗を検査する摩耗検査装置であって、シーブ5のアンダーカット部8の一部の領域を特殊カット部9に形成し、この特殊カット部9は、その縦断面の幅寸法が下端に行くにしたがって次第に小さくなる形状から成っている。【選択図】図6
