PROBLEM TO BE SOLVED: To provide a suspension device which is directed to improvement of rigidity of an area near a joint part between a side member and a suspension cross member and weight reduction.

SOLUTION: A suspension device 10 according to one embodiment of a technology of the disclosure includes: an upper arm 14; a lower arm 16; and a leaf spring 40 which is disposed so as to extend in a vehicle width direction and includes an end part arranged in the lower arm. A main cross member 30 (housing an intermediate part of the leaf spring) of a suspension cross member 28 is connected to a side member 26 through a hollow bracket 36. The hollow bracket has a bump rubber 64 at a position facing the lower arm. The hollow bracket side of the bump rubber 64 includes a reinforcement rib 62.
