PURPOSE: An object conveying wheel is provided to move a heavy object and to be located on a space with a low height. CONSTITUTION: An object conveying wheel comprises a load support plate(100), a loop-type rolling unit(300) and a guide unit(400). The load support plate is formed in order to support the load of a sliding window or a sliding door. The loop-type rolling unit is wound on the load support plate to be rotated around it if an object(1) moves along a fixed unit(2). The loop-type rolling unit comprises a plurality of rolling members(310) and a link unit(320) for connecting the rolling members. The link unit is formed so that the rolling members are arranged on the surface of the load support plate at given intervals. The guide unit guides the loop-type rolling unit not to slip to the left/right of the load support plate.
