A door lock for a motor vehicle door, and which is to be formed integrally with a motor vehicle door hinge, including a torsional spring supportable on one hinge half and having a weighting arm which extends parallel to a door hinge axis and projects beyond a door hinge height, at least three, substantially identical abutment rollers having a substantially heart-shaped cardioid cross-section at least along a portion of their height, pivotally supportable next to each other and in a spaced relationship relative to the door hinge axis on the abutment support, and cooperating with the weighting arm of the torsional spring for defining indexing positions in which the door can be retained during its opening movement, and three bearing axles for supporting the abutment rollers on the abutment support and arranged on the abutment support of a distance from each other, which is less than the largest diameter of the cross-section of the abutment rollers.
