PROBLEM TO BE SOLVED: To provide a supporting structure of a suspension device consisting of a double axle suspension capable of enhancing the assembly/disassembly workability of a wheel bearing and a constant velocity joint. SOLUTION: In the supporting structure of the suspension device, a wheel side knuckle 1 bearing the turn of a wheel and a vehicle body side knuckle 4 bearing the vertical movement are split into two, and the wheel side knuckle 1 rotatably supports the wheel via a wheel bearing 2, and is turnably connected to the vehicle body side knuckle 4 via upper and lower turning mechanisms 5, 6, the upper turning mechanism 5 comprises an upper pivot 21 separably coupled with a fixed shaft 20 coupled with the vehicle body side knuckle, and an upper supporting bearing 22 arranged between the upper pivot 21 and a cylindrical part 1b, the fixed shaft 20 is separably coupled therewith from the outside in the radial direction of the vehicle body side knuckle 4, and the upper supporting bearing 22 has a self-lifting structure fixed in the axial direction with respect to the upper pivot 21 in a pre-loaded condition.
