A supporting device is provided, which includes: a supporting arm having a gas spring and used for a display to be disposed thereon; a base for the supporting arm to be pivotally connected thereto; and an adjusting unit. The adjusting unit includes a worm disposed to the base and rotatable around its own axis; a shaft disposed to the base and separated from the worm; a worm wheel disposed around the shaft; and a connecting board having a fixing end fixed to the worm wheel and a pivot end pivotally connected to the gas spring. The pivot end and the shaft define a central line. Therefore, the worm is rotated to cause the worm wheel to rotate so as to cause the connecting board to pivot around the shaft, thereby adjusting the angle between the central line and the gas spring and hence the tilting angle of the gas spring.
