An electrically controlled window regulator for raising and lowering a mobile window of a motor vehicle door, and in which a slide rigidly connectable to said window is slidably mounted on a guide rigidly connectable to a support of said window, and is reciprocated by a flexible screw consisting at least partially of a precompressed spring extending through a rigid tubular member connected rotatably to said window support. The tubular member is provided with an inner volute with circulating balls coupled to the precompressed spring, and electrical drive means are provided to rotate the tubular member about its axis relative to said window support in one direction and to other.
