To provide a pulling-out auxiliary tool that can pull out a pulley and a flywheel while preventing the flywheel from being scratched.SOLUTION: A pulling-out auxiliary tool, which is used together with a puller in order to pull out in a pulling-out direction a pulley of a driving machine of an escalator and a flywheel fixed to the pulley from a rotary shaft body of the driving machine, comprises: a contacting part that contacts an inside surface pointing in an opposite direction of the pulling-out direction of the flywheel; an extending part that extends to the outside of an outer periphery part of the flywheel, from the contacting part toward the outer periphery part; and a pair of acting parts positioned at both side across the rotary shaft body at an end part closer to the outside than the outer periphery part in the extending part and formed so that a pair of claws of the puller are hung on the parts respectively.SELECTED DRAWING: Figure 4
【課題】フライホイールに傷がつくことを抑制しながらプーリーとフライホイールとを引き抜くことができる引抜補助具を提供する。【解決手段】引抜補助具は、エスカレーターの駆動機のプーリーとプーリーに固定されたフライホイールとを駆動機の回転軸体から引抜方向へ引き抜くためにプーラーと共に使用する引き抜き補助具であって、フライホイールの引き抜き方向とは反対を向く内側面に接触する接触部と、接触部からフライホイールの外周部へ向かって外周部よりも外側へ延びる延出部と、延出部における外周部よりも外側の端部において回転軸体を挟んだ両側に存在し、プーラーの一対の爪がそれぞれ掛けられるように形成された一対の作用部と、を備えた。【選択図】図4
