Structure for vehicle body rear portion

摘要

A structure for a vehicle body rear portion has a rear pillar (21), a rear wheel arch (15), a damper stiffener (22) which is connected so that the load of the damper (18) transmitted through the rear wheel arch (15) is dispersed to the rear pillar (21), and a brace (23) which is connected from the rear wheel arch (15) to the rear pillar (21). The brace (23) has a front surface section (31) which faces forward, a side surface section (32), and a rear surface section (33) which faces the front surface section (31). A front ridge line section (35) and/or a rear ridge line section (36) reaches the rear pillar (21) from the rear wheel arch (15).

主权项

1. A rear vehicle body structure comprising:
a rear pillar of a rear vehicle body section of a vehicle; a rear wheel arch disposed underneath the rear pillar; a damper stiffener extending vertically between the rear wheel arch and the rear pillar in such a manner that loads transmitted to the rear wheel arch and transmitted from the rear wheel arch to a damper are dispersed to the rear pillar; and a brace extending in a rearward direction of the vehicle continuously from the damper stiffener and extending vertically upward from the rear wheel arch to the rear pillar, wherein the rear wheel arch has a joining arch flange projecting in a radially-outward direction of the vehicle, wherein the brace has a front surface section located in a front portion of the brace to face in a forward direction of the vehicle, a side surface section extending rearwardly continuously from the front surface section, a rear surface section extending continuously from the side surface section to be located in a rear portion of the brace, the rear surface section being opposed to the front surface section, and a convex or concave-shaped horizontal bead section provided on a lower portion of the front surface section or on a lower portion of the rear surface section, wherein the brace has at least one of a front flange bent from a front end of the front surface section to extend in the forward direction of the vehicle and a rear flange bent from a rear end of the rear surface section to extend in the rearward direction of the vehicle, wherein at least one of the front flange and the rear flange has a brace joining portion joined to the joining arch flange in superposed relation to the joining arch flange, wherein the lower portion of the brace having the horizontal bead section provided thereon is a portion which is superposed on the joining arch flange and on which the brace joining portion is formed, and wherein at least one of a front ridgeline portion defined by the front surface section and the side surface section and a rear ridgeline portion defined by the side surface section and the rear surface section extends from the rear wheel arch to reach the rear pillar.
