PROBLEM TO BE SOLVED: To provide a bearing part degradation inhibition device capable of reducing wear of a bearing part caused by a tensile force of a driving belt.SOLUTION: According to the invention, a passenger conveyor has an end bracket 8 which is attached to a side surface of a drive motor 1 so as to face a flywheel 3. A bearing part 7 rotatably supports an output shaft 1a of the drive motor 1 and includes: an inner ring 7a attached to the output shaft 1a of the drive motor 1; an outer ring 7b fixed to the end bracket 8; and a plurality of bearing balls 7c provided between the inner ring 7a and the outer ring 7b. A bearing part degradation inhibition device includes: a holding part which holds the end bracket 8; a drawing part which draws the holding part in a direction in which the end bracket 8 separates from the side surface of the drive motor 1; and a fixing part which holds the drawing part and is fixed to the flywheel 3.SELECTED DRAWING: Figure 4

    【課題】駆動ベルトの張力に伴う軸受部の損耗を低減させることができる軸受部劣化抑制装置の提供。【解決手段】本発明は、乗客コンベアが、フライホイール3に対向するように駆動モータ1の側面に取り付けられたエンドブラケット8を備え、駆動モータ1の出力軸1aを回転自在に支持する軸受部7は、駆動モータ1の出力軸1aに装着される内輪7aと、エンドブラケット8に固定される外輪7bと、内輪7aと外輪7bとの間に設けられる複数の軸受球7cとを有するものであり、エンドブラケット8を把持する把持部と、エンドブラケット8が駆動モータ1の側面から離隔する方向に把持部を引き出す引き出し部と、この引き出し部を保持し、フライホイール3に固定される固定部とを備えている。【選択図】図4
