における踏段チェーン伸び検出装置。A push plate for switch operation is positioned and fixed to a tension rod that constantly tensions the step chain by pulling a movable driven wheel with a spring force, and a tip roller is attached to the push plate to operate a switch that rides on the push plate. A limit switch is provided that operates when the step chain comes off due to movement of a predetermined stroke to detect elongation exceeding the allowable limit of the step chain, and the push plate has a limit switch actuating part that is smaller than the radius of the roller at the tip end of the step chain, and that the roller A step chain elongation detection device for a passenger conveyor, characterized in that an elongated hole longer than the axial length of the limit switch is provided in accordance with the initial set position of the limit switch tip roller with respect to the push plate.
