An elastic bush has a recess which is provided in an inner portion, in a vehicle longitudinal direction, of the outer peripheral surface of the elastic bush and which is recessed outward in the vehicle longitudinal direction. A cylindrical section of an axle beam has a protrusion-shaped stopper which protrudes outward in the vehicle longitudinal direction from an inner portion, in the vehicle longitudinal direction, of the inner peripheral surface of the cylindrical section, and which is inserted into the recess with a gap provided between the stopper and the bottom surface of the recess. Thewall thickness, in a radial direction, of the elastic bush at the recess is less than or equal to half the wall thickness, in the radial direction, of the portion of the elastic bush, which is adjacent to the recess.
弹性衬套具有在其外周面的车辆长度方向内侧的部分朝向车辆长度方向外侧凹陷的凹部。轴梁的筒状部具有从其内周面的车辆长度方向内侧的部分朝向车辆长度方向外侧突出,且在与所述凹部的底面之间隔开间隙的状态下插入所述凹部的凸状的止挡部。所述弹性衬套的所述凹部中的径方向的厚度为所述弹性衬套之中与所述凹部邻接的部分中的径方向的厚度的一半以下。
