To achieve flaw detection with high accuracy in a simple device and to improve the workability.
A moving handrail flaw detection device S for detecting a flaw in a moving handrail 2 of an escalator 100 includes: an X-ray device 4; and a moving distance measuring device 7 for measuring the travel of the X-ray device 4. The moving distance measuring device 7 includes: a speed reduction mechanism 40 for moving the X-ray device 4 at a constant speed; and a second roller 27. The moving distance measuring device 7 includes: a measuring part 7a disposed on the upside across a moving handrail 2; a driving part 7b located at the lower part; and a second latch-lock 18 connecting both parts to each other. The measuring part 7a is provided with an optical mouse 8 for measuring the travel and a first roller 14, and the driving part 7b is provided with the speed reduction mechanism 40 and the second roller 27.
