<p>To prevent the displacement of a detection wire. A holder 11 is formed with an arrangement path assembly 14 including two through paths 15F, 15R arranged one before the other, a communication path 16 and two exposed paths 17L, 17R arranged side by side. A wear detection probe 10 is assembled by fitting a detection wire 18 into the arrangement path assembly 14. Since the detection wire 18 is fitted in the arrangement path assembly 14 having bent paths, it is caught at the bent portions of the arrangement path assembly 14 even if a pulling force acts thereon. Thus, there is no likelihood that the detection wire 18 is displaced. <IMAGE></p> |
