The invention provides a rear suspension structure capable of coordinating bending rigidity and torsional rigidity. The hub frame (14) is provided with a front arm part (30) and a rear arm part (32), wherein the front arm part (30) extends towards the front of the vehicle and towards the inner side of the vehicle compared with an axle (A) of a rear wheel, and the rear arm part (32) extends towards the rear of the vehicle. The rear arm section (32) is connected to a cross member (16) extending in the vehicle width direction further toward the vehicle rear than the axle (A). The transverse beam is connected to a vehicle rear end (25) of a trailing arm (12) extending in the vehicle front-rear direction. The vehicle front end of the trailing arm (12) is connected to the vehicle body through a first bush (24). The front arm part (30) is connected with a front arm mounting part (34) arranged on the trailing arm (12) through a second bush (38). A first support shaft (23) of the first bush (24) and a second support shaft (39) of the second bush (38) have axial directions arranged in different directions from each other.

    本发明提供一种能够协调弯曲刚性和扭转刚性这两者的后悬架构造。轮毂架(14)具有与后轮的车轴(A)相比向车辆前方且向车辆内侧方向延伸的前臂部(30)、和向车辆后方延伸的后臂部(32)。后臂部(32)与车轴(A)相比在车辆后方与沿车宽方向延伸的横向梁(16)连结。横向梁与沿车辆前后方向延伸的拖曳臂(12)的车辆后方端部(25)连结。拖曳臂(12)的车辆前方端部通过第1衬套(24)与车身连结。前臂部(30)通过第2衬套(38)与设于拖曳臂(12)的前臂安装部(34)连结。第1衬套(24)的第1支承轴(23)和第2衬套(38)的第2支承轴(39)具有轴向沿彼此不同的方向配置的轴向。
