差（個人差）が生じるようなことはない。Since the present invention has been configured as described above,
The following effects are obtained. (1) Since the wear amount of the rail head is measured based on the upper neck of the rail head,
Rail wear measurement rulers can also be installed where cables, snowmelters (heaters), points, etc. are attached. (2) Since a bearing that rolls on the upper neck of the rail is attached to the tip of the arm, the rail wear measurement ruler can be easily installed on the portion of the rail head to be measured. (3) Since the magnet is attached to the part of the arm that comes into contact with the side of the rail head, the rail wear measurement ruler can be strongly fixed to the part of the rail head to be measured.
The rail wear measurement rule never shifts during the measurement. Moreover, the measured value of the wear amount of the rail head is displayed through a window frame provided on the digital measuring instrument and can be read at a glance, so that the measuring accuracy is accurate, and errors (individual differences) vary depending on the measurer. Nothing happens.
