PROBLEM TO BE SOLVED: To provide a stop device for an opening closing door, which can suppress a force required for the opening of the opening/closing door in normal times, without complicating a structure, and which surely closes the opening/closing door in case of fire. SOLUTION: The stop device is constituted in such a manner that a self-closing type sliding door as the opening/closing door is kept in a fully opened state by making a leaf spring 24 lock a roller 26 of the sliding door. A push-out member 57 does not operate in normal times, and turns to a closing side when receiving a signal from a fire detector in case of fire, so as to push out a bracket 25 of the sliding door under the fully opened state to the closing side.
