Workbenchis for operator performing interior maintenance of casing, and laid between casingswhen separating casings. A pair of first supporting portionsare arranged parallel between casings so as to be able to horizontally support workbench bodywhen casings are in separating state. A pair of second supporting portionsare arranged parallel above bottom frameof one casing, and support one ends of first supporting portionswhen workbench bodyis in horizontal state. A pair of third supporting portionsare arranged parallel above bottom framewith one ends of the third supporting portions, to which the other ends of first supporting portionsare pivotally fixed, overhanging from bottom frame. Wiring holding sectionof wiring ductaccommodating and protecting wires in casingholds wires under workbenchbetween casings in separating state.

When moving casing accommodating electronic equipment for maintenance of electronic equipment, stability of casing is maintained and safety is ensured. Casing separation mechanismseparates and connects a pair of casings. A pair of rail portionsare set in bottom frameof one casingwith rail portionsoverhanging from frame. A pair of rail portionsextend from one ends of rail portionsand retract into rail portionsso as to be able to stop during movement of rail portionsby rail movement mechanism. A pair of rail portionsare set in bottom frameof other casingwith rail portionsoverhanging from frame, and extend from one ends of rail portionsand retract into rail portionsso as to be able to stop during movement of rail portionsby rail movement mechanism.
