Rear suspension structure

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 s
