Abstract: In a door fastener for motor vehicle doors which can be assembled independent of the door hinges and whose door holding bar, which is formed by means of a sheet metal material blank, cooperates with a torsion bar spring supported in a holder housing formed from a folded sheet metal material blank, the shaft of the torsion bar spring is supported at the side walls of the holder housing of a bearing shell which made of a maintenance-free, self-supporting material, bridges the holder housing and is secured at the latter against a movement in the axial and radial directions.

Abstract: In a door fastener for motor vehicle doors, whose rigid door holding bar, which is fixed at a door arrangement part, penetrates a holder housing in the other door arrangement part and is supported on the one hand against a rigidly supported abutment roller and is acted upon by means of a loading roller which is supported on the free loading arm of a torsion bar spring supported in the holder housing, the two rollers are equipped on both sides with a lubricant reservoir, which is accommodated in caps which are clipped on on the front sides of the rollers and is sealed relative to the respective bearing axis of the roller by means of sealing lips constructed at the caps.
