The invention relates to a chain extension detection device of a passenger conveyor, which can accurately detect the extension of a chain. The chain elongation detection device includes: a support member that rotatably supports one of a pair of sprockets on which a chain to be subjected to elongation detection is erected, and that supports the one of the sprockets so that the distance between the one of the sprockets and the other of the sprockets can be changed; a biasing member that biases in the direction in which the tension of the chain between the pair of sprockets increases via the support member; and a chain elongation detection part that outputs an elongation detection signal indicating that the elongation of the chain exceeds a predetermined elongation when the amount of movement of the support member in the direction from a predetermined reference position exceeds a predetermined amount of movement.
本发明涉及一种乘客输送机的链条伸长检测装置,能够准确地检测链条的伸长。该链条伸长检测装置具备:支承部件,将架设有伸长检测对象的链条的一对链轮中的一方的链轮支承为能够旋转,且将一方的链轮支承为能够改变与另一方的链轮之间的距离;施力部件,经由支承部件朝一对链轮之间的链条的张力变高的方向施力;以及链条伸长检测部,在上述方向上的支承部件从规定的基准位置起的移动量超过了规定移动量的情况下,输出链条的伸长量超过了规定伸长量的含义的伸长检测信号。
