FIELD: automotive industry, car bodies. SUBSTANCE: car body tailgate aperture is provided with lower load bearing unit - still 3 including floor panel, floor crossmember, aperture lower panel and crossmember stiffener interconnected to form double box section. Each pillar 1 has stiffener connected with its outer and inner panels formed respectively by rear portions of outer and inner panels of side. All load-bearing units are connected into common load-bearing unit of double-box cross section with closing of outer and inner outlines and with forming of middle closed outline. Closed outer outline of aperture on lower corner sections is formed by connecting side outer panel through floor panel with floor crossmember, and closed inner outline of aperture, by connecting side inner panel with flow panel. In upper corner section, closed middle outline of aperture is formed by connecting end face of roof beam with upper end of pillar stiffener, pillar stiffener is connected in lower corner section with end face of aperture lower panel. Side inner panel is made in height equal to upper half of pillar and is provided with cover plate in rear portion made over entire height of pillar. Each pillar has aperture side panel passing downwards from level of upper hinge and connected with inner flat of pillar stiffener. Double box section is formed by connecting side panel of aperture with outer panel of side and with cover plate of side inner panel connected in its turn with pillar stiffener. EFFECT: increased rigidity and strength of tailgate aperture, reduced diagonal deformations owing to reinforcement of corner sections. 3 cl, 14 dwgF
