PROBLEM TO BE SOLVED: To provide a control mechanism for an electric lock capable of recognizing locking and unlocking from the indoor side by the position of the angle of a thumb-turn. SOLUTION: The first gear 14 connected to rotational-angle detecting mechanisms respectively, the second gear 11 engaged and rotatably borne to the first gear 14 and the third rotatably borne gear 12 in the same axis as the second gear mutually independently are installed to a micromotor 16 through a decelerating mechanism 15, and a magnet clutch 24 is constituted between these second and third gears while a locking lever 13 in which a free end is faced to a stepped section 25 formed to a dead bolt 1 in a manner that the free end can be engaged from the inside and a base end is linked with the third gear 12 through a spring member, a stopper 36 controlling the range of the angle of rotation of the locking lever 13 and the fourth gear 29 engaged with the third gear while being connected to the thumb-turn are mounted.
