The invention relates to a transporter of glass base plate, which is formed by lower bearing base, lower roller wheel, upper bearing base, upper roller wheel, positioning support and positioning element. Wherein, the lower roller wheel is axially connected to the lower bearing base; the upper bearing base is mounted above the lower bearing base; the upper roller wheel is axially connected to the upper bearing base and meshed with lower roller wheel; the positioning support is arranged on the upper bearing base and has a groove hole on the top wall of positioning support; the positioning element is inside the groove hole to support the upper roller wheel, to press down the upper roller wheel, to improve the friction force between the upper and lower roller wheels and the glass base plate.
