Abstract
A rotary drum for a gear control device for a motor-vehicle gearbox is provided. The drum is rotatable about a rotation axis and includes two guide channels on a cylindrical lateral surface of the drum arranged to guide in a slidable manner at least one follower member. The rotary movement of the drum about the rotation axis is converted into translatory movement of said at least one follower member. A series of positioning notches are provided on the cylindrical lateral surface of the drum and spaced apart angularly along a circumference of the drum for snap-engagement by a stop member associated with the drum. The positioning notches are axially interposed between the two guide channels. Two rings of radial through-holes are provided on the cylindrical lateral surface of the drum, each axially interposed between the positioning notches and a respective guide channel.
