PROBLEM TO BE SOLVED: To provide a laser optical axis balance adjusting mechanism for laser marking device which is capable of delicate balance adjustment and attaining high adjustment efficiency and downsizing. SOLUTION: This laser marking device is provided with a laser unit holder 14 supported so as to be oscillatable by a gimbal mechanism, and one or more laser units 20a mounted on the laser unit holder 14, wherein an eccentric weight is rotatably-fitted on the outer periphery of the laser unit holder 14. At the outer periphery of the laser unit holder 14 and in the direction parallel to an oscillating plane, a sub weight 53 is mounted which changes the center of gravity by screw fastening.
