To provide a suspension structure capable of making a vehicle height sufficiently high by reducing constraints of adjustments of the vehicle height.

In this suspension structure, an air spring 4 and a leaf spring 5 are jointly used. An eye 5a formed at an end part on a front side of the vehicle of the leaf spring 5 is pivotally supported on a horizontal pin 7 of a bracket 6 mounted on a chassis frame 1 side via a metal bushing 8. An end part on a rear side of the vehicle of the leaf spring 5 can be guided in the vertical direction by a guide member 9b of the bracket 9 mounted on the chassis frame 1.
