置。 Friction in a braking device comprising a braking wheel, a brake element having a friction material facing the braking wheel, and a pressing device capable of pressing the brake element toward the braking wheel so as to press the friction material against the braking wheel. In the material wear detection device, the brake element holds a light-emitting part of a light-emitting optical fiber cable that can irradiate light from a light source toward the brake wheel, and a light emitting part that emits light from the light-emitting part and illuminates the brake wheel. burying light-receiving portions of a plurality of light-receiving optical fiber cables into which reflected light can enter, such that the light-receiving portions sequentially appear on the surface of the brake element facing the brake wheel as wear of the friction material progresses; A wear detection device for a friction material in a braking device, characterized in that the light receiving optical fiber cables are connected to a detector that detects the light receiving state of the cables.
