Summary:PROBLEM TO BE SOLVED: To provide an electric lock device which can be post-fitted to an existing thumb-turn lock and can be used for multiple types of thumb-turn locks with different shapes of knobs. SOLUTION: A plurality of slits 22, 23, 24 with different widths are formed in a transmission member 6 in a point symmetrical shape which radially extend through the rotating center of the transmission member 6 and are arranged symmetrically with respect to the center so that the slits 22, 23, 24 can be selectively used according to the thickness of the knob of the thumb-turn lock. Therefore, since the transmission member does not need to be prepared according to the thickness of the knob, the number of parts can be reduced, a part control operation and installation operation are facilitated, and cost can also be reduced.
