Abstract: In an automobile rear body structure, a rear windshield glass is separated into two at a predetermined height. The upper half of the rear windshield glass is fixedly connected to a pair of rear pillars disposed on both sides of the rear body structure and to a roof panel to which a rear header extending in a direction widthwise of an automobile vehicle is rigidly secured for reinforcement of the roof panel. The lower half of the rear windshield glass is fixedly connected to a trunk lid, which is hingedly connected to the rear pillars for opening or closing a trunk room. Such a construction provides a relatively wide opening through which various luggages can be readily loaded in or unloaded from the trunk room.
