PROBLEM TO BE SOLVED: To provide a suspension device with a vehicle height adjustment function which is compact in size, and excellent in mountability to a vehicle.SOLUTION: A suspension device with a vehicle height adjustment function has a coil spring 2 which supports a vehicle body 1, an annular upper-side spring sheet 3 which receives an upper end of the coil spring 2, and a linear actuator 6 which changes a height position of the vehicle body 1 with respect to the upper-side spring sheet 3. The linear actuator 6 has an outer ring member 20 having a spiral protrusion 26 at an internal periphery, a rotating shaft 21 which is arranged in a center of the outer ring member 20, an electric motor 13 which rotationally drives the rotating shaft 21, and a planetary roller 22 which is assembled between the internal periphery of the outer ring member 20 and an external periphery of the rotating shaft 21.SELECTED DRAWING: Figure 1
