PURPOSE: A measuring device of a shaft is provided to measure the length and the depth of the center in a shaft simultaneously and conveniently, and to reduce working process. CONSTITUTION: A V-block(350) is installed on a table to settle a shaft of a processed pallet, and a moving plate(260) is transferred by an air cylinder(240). A symmetrical guide shaft(280) is guided in the moving plate by a housing(270), and inserted to the center of the shaft. Plural signal gauges(330,331,370) are contacted to the guide shaft, and the guide shaft is contacted to the shaft by operating the cylinder. The signal gauges in both sides detect the length of the shaft and the depth of the center conveniently and simultaneously by measuring displacement of the guide shaft according to size tolerance of the shaft and comparing the measured value with the reference value.
