PROBLEM TO BE SOLVED: To provide a turning drive mechanism for a laser marking device having a coarse motion mechanism having high turning speed and a fine adjustment mechanism capable of performing accurate turning angle adjustment, miniaturizable and weight-reducible by utilizing a power source for laser line irradiation for turning driving, and capable of preventing generation of an accident such as falling of a device caused by entanglement of wiring of a power source adapter by restricting a turning operation range during remote operation. SOLUTION: This turning drive mechanism for the marking device is constituted as follows: a turning base member is supported turnably to a fixed base member; a driving base member and a coarse motion turning ring member are interposed turnably in the middle between the turning base member and the fixed base member; the coarse motion turning ring member is turned and driven by an electrically-driven coarse motion turning drive mechanism provided on the driving base member; and the turning base member is turned and driven by an electrically-driven slight movement turning drive mechanism provided on the driving base member.
