がある。With the use of guide pulleys and drive pulleys, it is inevitable that the U-grooves or V-grooves will wear out during use. This wear occurs not only at the bottom of the groove, but also at the side of the groove due to the cutting surface not being coincident with the surface including the pulley and the vibration of the cutting cable during cutting. As the wear progresses, the rubber portion having the U-groove or the V-groove is replaced. However, if the wear is missed, sometimes the wear progresses to the steel portion 9 in FIGS. 2 and 3, and the pulley itself must be replaced. May be lost. Further, as shown in FIG. 5, as the wear of the side portions of the U-groove or V-groove progresses, the vibration of the cutting cable during cutting may cause the guide portion of the groove to be bent and the cutting cable to come off from the groove.
