PROBLEM TO BE SOLVED: To provide an automatic switchgear of a fitting capable of manually easily opening-closing the fitting, even if the automatic switchgear of the fitting is provided for automatically opening-closing the fitting.SOLUTION: This automatic switchgear of the fitting comprises a rack 10 fixed to the openable-closable fitting 3, a pinion 16 meshing with the rack 10, a holding member 18 for rotatably holding the pinion 16, a rack 11 fixed to an openable-closable fitting 4, a pinion 17 meshing with the rack 11, a holding member 19 for rotatably holding the pinion 17 and a rotational driving mechanism for rotatingly driving the pinions 16 and 17. The holding member 18 can move between a meshing position for meshing the rack 10 and the pinion 16 and a release position for releasing meshing of the rack 10 and the pinion 16, and the holding member 19 can move between a meshing position for meshing the rack 11 and the pinion 17 and a release position for releasing meshing of the rack 11 and the pinion 17. |
