PROBLEM TO BE SOLVED: To solve the problems that a pin sometimes comes off to prevent a step from being mounted during maintenance in the case of a division type mouthpiece part and that a step cannot be mounted at an inclination part of an escalator in the case of an integral structure type mouthpiece part: there is the former and the latter as a fixing method of a foot step for an escalator.SOLUTION: In a fixing method to a shaft, a mouthpiece part is an integral structure, and the shape of a resin collar sliding with the shaft is circular to be an egg shape having a partial protrusion. A movable step has an egg-shaped mouthpiece part of the same shape as the resin collar, and is fixed by a screw after the collar is inserted. As for the resin collar, when the movable step is inserted, the resin collar is guided along the egg-shaped inclination part of the same chape as the resin collar provided in the movable step, and the resin collar is fitted into the egg-shaped mouthpiece part.SELECTED DRAWING: Figure 1

    【課題】エスカレーターの踏段などの固定方法として、口金部が分割タイプのものと、口金部が一体構造であるものとがある。前者は、メンテナンス時にピンが外れてステップを取り付けられないことがある。後者は、エスカレーターの傾斜部において取付けを行うことができない。【解決手段】軸への固定方法は、口金部は一体構造とし、軸と摺動する樹脂製のカラーの形状を円形に一部突起を持たせた卵型とする。移動段には樹脂製のカラーと同一形状の卵型の口金部を持たせ、このカラーを挿入後、ねじで固定する。樹脂製のカラーは移動段を挿入する際に、移動段に設けられた樹脂製のカラーと同形状の卵型の傾斜部に沿って樹脂製のカラーを誘導し、卵型の口金部に樹脂製のカラーを嵌め込む。【選択図】 図1
