FIELD: machine building.
SUBSTANCE: invention relates to a driving mechanism for actuation of a slipping element, comprising driving gear (1), a time unit indicator, skipping element (6) made integral with said indicator and coaxial with said driving gear (1), to which said slipping element (6) is connected by means of spring (8), cam (12) intended for rocking motion of anchor lever (20) to release slipping element (6) once per unit time. According to invention, cam (12) and slipping element (6) have separate rotation axes, said drive mechanism additionally comprises intermediate gear mechanism, kinematically connecting driving gear (1) with cam (12), and anchor lever (20) has four separate arms (20a, 20b, 20c, 20d), two (20a, 20b) of said four arms form feelers, designed to interact with cam (12), and two other arms (20c, 20d) form trigger arms intended for consecutive sequential blocking and release of slipping element (6) once per unit time.
EFFECT: disclosed is a mechanism for activating a slipping element.
