A mobile base includes a main body having a first side formed with two first foot portions and a second side formed with two second foot portions, two fixing rollers each mounted on a respective first foot portion, an adjusting plate mounted between the second foot portions, an adjusting roller mounted on the adjusting plate to move therewith, and an adjusting unit mounted between the second foot portions and urged on the adjusting plate to press the adjusting plate to move. Thus, the adjusting unit is hidden in a space between the first side rack and the second side rack, so that the adjusting unit is not operated unintentionally.
