PROBLEM TO BE SOLVED: To provide interrupting equipment which can be installed in a necessary place when necessary by virtue of easiness of conveyance, and which can be temporarily or periodically and appropriately opened/closed. SOLUTION: An air blower is mounted in a box body, the one lateral wall of which is provided with an opening, and an expandable/contractible bag-like interrupting machine is mounted inside the box body in such a manner as to surround an exhaust port of the air blower. When air is supplied into the interrupting machine by operating the air blower, the interrupting equipment is substantially horizontally elongated from an opening of the box body so as to maintain a tensioned mode. When the operation of the air blower is stopped, air pressure inside the interrupting machine is decreased so as to relax the tensioned mode. The interrupting equipment is constituted as above.
