ABSTRACT:
A shade roller includes a roller, a first tube slidably received within the roller and a second tube having a part of the first tube securely received therein. Due to the extendable characteristics of the first tube and an outer diameter of the second tube being manufactured to be the same as that of the roller, a user is able to adapt to different widths of different windows and roll up or down a shade which is originally wound around the shade roller evenly.
