PROBLEM TO BE SOLVED: To provide a rotary folding door having a structure for easily setting a position of a projection strip of a cover member in a position for blocking up clearance between a slave door and a master door, without damaging the projection strip of the cover member when opening and closing a rotary door, in the cover member stretched in an inside part of the slave door and the master door. SOLUTION: The two projection strips 57a and 57b projecting outward along a vertical edge, are laterally asymmetrically arranged from a central position in the width direction on a semicylindrical outside surface of the respective cover members 50 and 50. In operation for rotatably opening and closing a first door and a second door, the mutual projection strips of the respective cover members are put in a noncontact state, and in a state of being arranged on one vertical plane by closing both doors, the projection strip of the other cover member enters a recessed part between the projection strips of the cover members, and blocks up the clearance S between the first door 5 and the second door 4 by being alternately arranged.
