[Effects of the Invention] In the present invention, since the entire digital measuring instrument is strongly fixed to the tongue rail by the magnetic force of the magnet, the measuring instrument does not deviate during the measurement, and the measurement accuracy is improved. Is accurate, and there is no possibility that errors (individual differences) may occur between operators. In the present invention described in the claims, the entire digital measuring instrument is strongly fixed to the tongue rail by the magnetic force of the magnet, so that the digital measuring instrument never shifts during the measurement, and the measured value of the tongue rail wear is reduced. Since it can be read at a glance through the window frame of the digital measuring instrument, the measurement accuracy is accurate, and no error (individual difference) is caused by the operator. According to the third aspect of the present invention, when the tong rail wear measuring device is set on the tong rail, the bearing can be rolled on the bottom of the tong rail, so that the setting is easy. According to the invention of claim 4, the inclined portion forms a gap between the bottom of the tong rail and the R surface connected to the abdomen, so that the cutting error of the R surface can be escaped, and the pressing plate can be moved to the bottom of the tong rail and Can be adhered to the abdomen. In the conventional caliper type measuring instrument, the wear amount can be measured only at two places of the tongue rail head width, whereas in the invention of claim 5, the slide machine frame is located at a plurality of holes provided on the setting plate. Since it can be slid accordingly, a single digital measuring device can accurately measure the wear amount at multiple locations along the tongue rail head width.
