摘要： A rear underbody which forms a rear-under section of a vehicle body is provided with a pair of rear floor side members disposed along a longitudinal direction of the vehicle body in respective vicinities of both end portions of the rear underbody in a transverse direction of the vehicle body. The pair of rear floor side members each forms an enclosed cross-sectional configuration which extends in the longitudinal direction of the vehicle body. A cross member which extends substantially straight in the transverse direction of the vehicle body is disposed apart from and under a rear floor pan between the pair of rear floor side members at respective substantially central portions of a pair of rear wheel house inners. Both end portions, in the transverse direction of the vehicle body, of the cross member are respectively welded to an inner surface of the inside wall portion, in the transverse direction of the vehicle body, of the rear floor side member. A lower-arm bracket which supports a rear lower arm is disposed in a central portion, in the transverse direction of the vehicle body, of a lower surface of the cross member. This causes vibration of the rear floor pan to be sufficiently controlled and causes road noise to be sufficiently reduced.

摘要翻译：形成车体的后下部的后底部设置有沿着车体的纵向方向沿着车身的纵向方向在相对于后底部的两个端部的相邻附近的横向方向上设置的一对后地板侧构件车身。所述一对后地板侧构件形成沿着车体的长度方向延伸的封闭截面构造。在一对后轮车厢内的相应的大致中央部分处，在一对后地板侧构件之间的后地板盘之间设置有与车身横向大致直线延伸的横梁。横向构件的横向方向上的两个端部分别在后方侧面构件的车体的横向方向上被焊接到内壁部的内表面。支撑后下臂的下臂支架设置在横梁的下表面的车身的横向方向的中心部分。由此，能够充分地控制后地板盘的振动，能够充分地减少道路噪声。
