PURPOSE: An apparatus for fixing a hub inside a rack in a mobile communication system is provided to freely exchange two hubs and reduce the cost for the exchange by not exchanging all brackets. CONSTITUTION: A bracket(100) is united with the lower part of a rack and has a securing surface where one hub is secured. The first fixing element(200) includes the first and second fixing units(210,220) vertically formed at points separated from the center of the bracket(100). The first fixing element(200) includes a rear fixing unit(230) formed at a point separated from the point where the first and second fixing units(210,220) face each other. The second fixing element(300) includes the third and fourth fixing units(310,320) formed in the same shape as the first and second fixing units(210,220). The gap between the third and fourth fixing units(310,320) is wider than that of the first and second fixing units(210,220).
