PROBLEM TO BE SOLVED: To provide a passenger conveyor safety device capable of coping with change of a height position of a drive chain, without division formation of an arm part.SOLUTION: A safety device of an escalator comprises: an arm part 20 to which a contact member 22 for contacting a drive chain 5 is attached; a ratchet wheel 40 attached coaxially with a terminal sprocket 4; and a stopper 41 actuating in linkage with rotation of the arm part 20 and capable of engaging with the ratchet wheel 40. During abnormality time of the drive chain 5, the stopper 41 actuates in linkage with the arm part 20 and engages with the ratchet wheel 40 and stops the terminal sprocket 4. The arm part 20 is extended in an inclined state to a linear part included in a drive locus of the drive chain 5, and on the arm part 20, plural holes 21 into which a support shaft on the contact member 22 can be rotatably and selectively inserted are formed, in the extending direction.

    【課題】アーム部を分割形成することなく、駆動チェーンの高さ位置の変更に対処させることができる乗客コンベアの安全装置の提供。【解決手段】本発明は、駆動チェーン5に接触する接触部材22が取り付けられたアーム部20と、ターミナルスプロケット4と同芯に装着されたラチェットホイール40と、アーム部20の回動と連動して作動し、ラチェットホイール40に係合可能なストッパ41とを備え、駆動チェーン5の異常時に、アーム部20と連動してストッパ41が作動してラチェットホイール40に係合し、ターミナルスプロケット4を停止させるエスカレータの安全装置において、アーム部20を、駆動チェーン5の駆動軌跡に含まれる直線部に対して傾いた状態に延設し、アーム部20に、その延設方向に沿って、接触部材22に設けた支持軸が回動可能に、選択的に挿入される複数の穴部21を形成してある。【選択図】図2
