PROBLEM TO BE SOLVED: To provide an indentation evaluation device and an indentation evaluation method capable of evaluating indentations more easily compared to the case of using an actual machine of a passenger conveyor.SOLUTION: An indentation evaluation device comprises a lower roller, an upper roller holding a test piece between itself and the lower roller, a weight unit brought into contact with the upper roller from above, and a holding unit. The holding unit holds the lower roller at a fixed position, holds the upper roller slidably in a vertical direction at an upper portion of the lower roller and holds the weight unit slidably in a vertical direction at an upper portion of the upper roller. The outer diameter of the lower roller is 100-220 mm and the outer diameter of the upper roller is 70-110 mm.SELECTED DRAWING: Figure 1

【課題】乗客コンベアの実機を用いる場合よりも容易に圧痕を評価できる圧痕評価装置及び圧痕評価方法を提供すること。【解決手段】圧痕評価装置であって、下部ローラと、前記下部ローラとともに試験体を挟む上部ローラと、前記上部ローラに上方から当接するおもりユニットと、保持ユニットと、を備え、前記保持ユニットは、前記下部ローラを一定の位置に保持し、前記上部ローラを前記下部ローラの上方において上下方向にスライド可能に保持し、前記おもりユニットを前記上部ローラの上方において上下方向にスライド可能に保持するように構成され、前記下部ローラの外径が１００〜２２０ｍｍであり、前記上部ローラの外径が７０〜１１０ｍｍである圧痕評価装置。【選択図】図１
