摘要： In order for a trailer hitch comprising a cross-member, which has its longitudinal direction extending transversely to a longitudinal direction of a vehicle and which can be connected to a body of a vehicle, a ball neck, which at a first end region is connected to the cross-member by means of a bearing unit and at a second end region carries a coupling ball, to be improved such that it has a lower weight, it is proposed that the cross-member is in the form of a hollow shaped body which varies in cross-sectional shape and has a central region and outer regions which adjoin the central region on both sides and extend as far as outer ends of the hollow shaped body, and that, starting from the outer ends, a cross-sectional shape of the outer regions has a cross-sectional area that increases progressively in the direction of the central region.
