To provide a measurement gage capable of measuring a chain elongation percentage for a passenger conveyor without visual observation.SOLUTION: A chain elongation percentage measurement gage 10 for a passenger conveyor measures an elongation percentage of a chain laid on the passenger conveyor, and is provided with: a base material 20; a reference hole 30 which is formed at a base end of the base material and into which a first roller pin 74 of the chain 73 fits; a measurement surface 40 which is formed at a tip of the base material and against which a second roller pin 75 away from the first roller pin of the chain by a prescribed pitch abuts; and windows 50 that are formed between the reference hole and the measurement surface so as to avoid interference with the roller pins 73 present between the first roller pin and the second roller pin.SELECTED DRAWING: Figure 3

    【課題】本発明は、目視に頼ることなく乗客コンベアのチェーンの伸び率を測定することのできる測定ゲージを提供する。【解決手段】本発明の乗客コンベアのチェーン伸び率測定ゲージ10は、乗客コンベアに張設されたチェーンの伸び率を測定するゲージであって、基材20と、前記基材の基端に形成され、前記チェーン73の第1ローラーピン74が嵌まる基準穴30と、前記基材の先端に形成された測定面40であって、前記チェーンの前記第1ローラーピンから所定ピッチ離れた第2ローラーピン75が当接可能な測定面と、を有し、前記基準穴と前記測定面との間には、前記第1ローラーピンと前記第2ローラーピンの間に存するローラーピン73を避ける窓部50を具える。【選択図】図3
