ROLLER UNIT HAVING INTEGRATED FASTENING PORTION

摘要

A roller unit having an integrated fastening portion includes a supporting shaft fastened to a containing body or a containing main body that can slide and having first and second flanges formed in multi steps with different outer diameters, a rotating body rotatably fixed to a side of the supporting shaft, and a washer coupled to a side of the rotating body to surround and fix the second flange, thereby preventing separation of the supporting shaft and the rotating body. Therefore, it is possible to more conveniently combine the supporting shaft and the rotating body and to prevent separation of the supporting shaft and the rotating body, whereby is possible to improve various functions.
