PROBLEM TO BE SOLVED: To provide a suspension arm supporting structure capable of increasing the rigidity of a vehicle body to support a joint of a suspension arm with a simple structure. SOLUTION: A joint 25 of a trailing arm 24 extending in the longitudinal direction of a vehicle body is arranged in a space held by a first supporting wall 23b inward of the vehicle width direction and a second supporting wall 23c outward of the vehicle width direction. When an end of a bolt 29 passing through the joint 25 is screwed to a collar nut 31 fixed to an inner surface in the vehicle width direction of the first supporting wall 23b, both ends of a support member 32 are stretched over a middle floor cross member 16 continuous to the inner surface of the vehicle width direction of the first supporting wall 23b, and an outer circumferential surface of the collar nut 31 is fixed to the support member 32. The mounting rigidity is increased by connecting the collar nut 31 to the middle floor cross member 16 via the support member 32 to effectively prevent deformation of the first and second supporting walls 23b, 23c input from the trailing arm 24 through the rubber bush joint 25 and the bolt 29.
