FIELD: machine building.
SUBSTANCE: invention relates to interlocked electromechanical drives. Drive (1) comprises screw (15) extending along longitudinal axis, nut (19), mounted on screw (15) and equipped with means (24) of connection with movable element (2), passive device (40) for blocking movable element (2) in the retracted position. Passive locking device (40) comprises lock actuation means, which can selectively occupy the first position, in which the lock prevents relative rotation of the screw and nut, which could lead to extension of movable element, and second position, in which nut screw rotation is free, wherein lock passes from one of first and second positions to another of first and second positions when movable element (2) passes beyond its retracted position.
EFFECT: reduced weight and reduced dimensions of the drive.
