Measurement method using the amount of wear measurement tool and the amount of wear measurement tool

摘要

PPROBLEM TO BE SOLVED: To correctly measure an abrasion of a hub in a stable state, and to measure the abrasion of both of the hub and a disc wheel. PSOLUTION: An abrasion measurement tool includes: a tool body 12; a hub abrasion measuring section 13; and a disc wheel abrasion measuring section 14. The hub abrasion measuring section 13 has a hub abutment surface 15 made to abut against a non-abrasion portion on a hub outer circumference wheel attaching surface 4 and a hub inner circumference wheel attaching surface 5 in the hub 2 for bridging a hub bolt 7, and measuring a gap interval between an abrasion portion of the hub outer circumference wheel attaching surface 4 or the hub inner circumference wheel attaching surface 5. The disc wheel abrasion measuring section 14 has a wheel-abutting surface 17 which abuts against a wheel outer circumference hub abutting surface 8 and a wheel inner circumference hub abutting surface 9 so as to bridge a hub non-abutting surface 10 in the disc wheel 3; and a measurement reference surface 18 facing the hub non-abutting surface 10, and measuring a gap interval between the hub non-abutting surface 10 in the disc wheel 3.
