To provide a tire wear sensor capable of measuring a wear degree of a tire tread without embedding, in the tire tread, a magnetic body, the cause of attracting an iron nail, etc., to a tread surface.SOLUTION: A tire wear sensor 1 disposed on an inside 21 of a tire 2 for detecting a wear degree of the tire 2 based on a change in magnetism, includes a magnet 11 disposed on the inside 21 of the tire 2, and a magnetic sensor 12 disposed closer to the rotation center O of the tire 2 than the magnet 11 and capable of detecting magnetism generated by the magnet 11. When a detection object part 24 of a tread 23 of the tire 2 comes into contact with the magnetic body 3 located on an outside 22 of the tire 2, the tire wear sensor 1 causes the magnetic sensor 12 to detect the magnetism generated by the magnet 11 so as to measure the wear degree of the tire 2.SELECTED DRAWING: Figure 1
【課題】トレッド部表面に鉄の釘などを引き寄せる原因となる磁性体をタイヤのトレッド部に埋め込むことなく、タイヤのトレッド部の摩耗度を測定できるタイヤ摩耗センサを提供すること。【解決手段】磁気の変化に基づいてタイヤ2の摩耗度を検知する、タイヤ2の内側21に配置されるタイヤ摩耗センサ1において、タイヤ2の内側21に配置された磁石11と、磁石11よりもタイヤ2の回転中心O側に配置され、磁石11が発する磁気を検知可能な磁気センサ12と、を有し、タイヤ2におけるトレッド部23の検知対象部24がタイヤ2の外側22に位置する磁性体3に接触したときに、磁気センサ12により磁石11が発する磁気を検知してタイヤ2の摩耗度を計測するタイヤ摩耗センサ1。【選択図】図1
