Abstract
There is provided a configuration that can precisely detect abrasion of brake shoes of a railway vehicle. A brake shoe abrasion detection unit includes: at least one abrasion detection RF tag that is attached at a position of an abrasion limit of a brake shoe of a railway vehicle tread brake or a position closer to a braking surface than the abrasion limit; and a reference RF tag that is attached at a position beyond the abrasion limit of the brake shoe.

A brake shoe abrasion detection unit of a railway vehicle, the brake shoe abrasion detection unit being attached to a brake shoe of a railway vehicle tread brake and detecting abrasion of the brake shoe, the brake shoe abrasion detection unit comprising:
- at least one abrasion detection RF tag that is attached at a position of an abrasion limit of the brake shoe or a position closer to a braking surface than the abrasion limit;
- a reference RF tag that is placed at a position further from the braking surface than the abrasion limit of the brake shoe;
- and
- a base sheet on which the at least one abrasion detection RF tag and the reference RF tag are provided at different positions in a thickness direction of the brake shoe, and on which an adhesive layer to be applied to the brake shoe is formed,
- wherein the base sheet includes a perforation formed between the at least one abrasion detection RF tag and the reference RF tag, the perforation being formed to be easily fractured compared to other portions of the base sheet.
