The plain bearing is a ready-to-install unit in that the cylindrical bush part of the flange bearing bush inserted in the bearing opening is deformed radially outwards and radially inwards by axially upsetting the front face and rests on the inner wall of the bearing opening and against the circumferential surface of the bearing pin without play. The front face is recessed behind the surface of the hinge housing part. One side of the plain bearing has an axial bearing element that exteriorly rests radially against the surface area of the hinge housing part surrounding the bearing opening and radially interiorly against an axial step of the bearing pin. The bearing pin is secured in a position in the axial direction.
