Zusammenfassung:To provide a measurement device capable of measuring changes in physical property of a belt while identifying measurement points on the belt.SOLUTION: The power belt transmission device is a belt that is laid between a first pulley and a second pulley to be rotatably moved. The power belt comprises: a belt containing a stress-emitting material in which the light emission state of the material changes depending on the magnitude of applied physical amount; a detection unit configured to detect light emitted from the stress-emitting material in the belt, which is configured to detect light signals emitted from multiple different points to which stress is given; and a processing unit that is configured to calculate a difference in multiple pieces of data using multiple light signals acquired from multiple points by the detection unit and to determine the state of the belt on the basis of the difference.SELECTED DRAWING: Figure 1 【課題】ベルトの測定部位を特定してベルトの物性変化を測定するための測定装置を提供することにある。【解決手段】第1のプーリと第2のプーリに架けられて回転移動されるベルトであって、ベルトには、加えられる物理量の大きさに応じてその材料の発光状態が変化する応力発光材料が含まれたベルトと、ベルトの応力発光材料から発せられる発光を検出する検出器であって、検出器はベルトに与える応力が異なる複数の部位からの発光信号を検出する検出器と、検出器により複数の部位から取得された複数の該発光信号による複数のデータの差分を求めて、差分を基にベルトの状態を判定する処理装置と、を有する動力ベルト伝達装置である。【選択図】 図1
