Claims

[Scope of utility model registration request]

A pair of thin plate annular electrodes are molded into an annular shape using an electrical insulator that easily wears out, and a groove corresponding to the wear limit is formed on the inner circumferential surface of the electrode, and the rotating shaft is fixed through the groove and comes into contact with the rotating shaft. In a sensor that detects abrasion of the shaft by making electrical contact between the electrode and the rotating shaft by abrasion of the groove edge of the molded electrical insulator, the abrasion detection sensor divided into a plurality of fan shapes is reassembled into an annular shape. A structure of a shaft wear detection sensor characterized by having an integral structure.
