PROBLEM TO BE SOLVED: To improve safety and appearance by enhancing the seismic performance of a cabinet rack with a simple and inexpensive configuration.SOLUTION: Four posts 5 are stood at corners of a bottom frame 4. A top frame is attached to the upper end of each post 5. Frame of a cabinet rack is constituted by the bottom frame 4, the post 5 and the top frame, and a housing chamber 8 of an electric apparatus is formed on the inside of the frame. The post 5 is provided with a duct 10 for wiring the cables of the electric apparatus. The duct 10 is formed by winding a metal plate in one direction by a folding line 14 extending in the longitudinal direction of the post 5. On the peripheral wall of the duct 10, an elongated wiring slit 14 is provided so as to open to the housing chamber 8 side, thus facilitating the loading and unloading of cables. Outer surface of the post 5 is formed smoothly by entraining the edge of the duct 10 to the inside of the post 5. |
