PURPOSE: A vibration preventing device of a corresponding bar in a machine tool is provided to solve problems caused by the rotational vibration of a target machining bar at low costs because bushings and elastic members are charged in the inside of a target machining bar supplying pipe and a fixed cap is fixed to a rear part of the target machining bar supplying pipe. CONSTITUTION: A vibration preventing device of a corresponding bar in a machine tool comprises bushings(50,52,54,56), a plurality of elastic members(62,64), and a fixed cap(70). The plurality of bushings is installed in a through-hole(25) of a bar supplying pipe(20). The target machining bar penetrates the through-hole in the central portion of the bushing. The plurality of elastic members is arranged in between the bushings in the inside of the through-hole of the target machining bar supplying pipe and pushes the bushings with elastic power. The target machining bar penetrates the through-hole of the fixed cap. The fixed cap is fixed to a rear part of the target machining bar supplying pipe so that the bushings and elastic members are not separated from the target machining bar supplying pipe.
