PROBLEM TO BE SOLVED: To provide a gimbal mechanism of a laser marking device capable of dispersing impact force applied to a ball bearing and releasing loads to members except for the ball bearing when the impact force is applied in a crossing direction with a central axis of the ball bearing. SOLUTION: This laser marking device comprises a laser unit holder 24 rockably supported by the gimbal mechanism 15, and at least one laser unit 30 attached to the laser unit holder 24. The gimbal mechanism 15 has a pair of an upper axis and a lower axis in the same direction. The gimbal mechanism 15 has a first axis 44 in one direction, a rocking body 18 and a second axis 47. The rocking body 18 is rockably supported by the first axis 44. The second axis 47 is parallel to the first axis 44 and supported by the rocking body 18. The laser unit holder 24 is rockably supported by the second axis 47 inside of the rocking body 18.
