CONSTITUTION: Roller assembly installed in a refrigerator comprises a roller(100), a magnetic bolt(200), a nonmagnetic fixing part(300), and a washer(400). A penetration hole(101) is formed on the center of the roller. The magnetic bolt passes through the penetration hole of the roller and is composed of a head(210) and a screw part(220). The head comprises a circular groove(230) formed on the center of the magnetic bolt. The screw part is fixed to a side(600) on which the roller assembly is to be mounted. The nonmagnetic fixing part is composed of a cylindrical body(310) press-fitted to the circular groove and a head(320) having a larger diameter than the diameter of the head of the magnetic bolt. The washer is interposed between the head of the nonmagnetic fixing part and the roller. |
