PROBLEM TO BE SOLVED: To provide a revolving door device allowing smooth passage even if the volume of traffic is increased. SOLUTION: The circumferential lengths of arcuate panels 6 and 7 provided for first and second partition panels 4 and 5 are set shorter than those of entrance sections 2b and 2c. Opening/closing panels 8 and 9, which can be freely displaced between a closing position along a cylindrical wall body 2 and a closing position to close a rotational-direction rear-side half portion of each of the entrance sections 2b and 2c, are provided. Thus, the opening/closing panels 8 and 9 close the entrance sections 2b and 2c in synchronization with the corresponding arcuate panels 6 and 7, while rotational-direction leading-side edges of the arcuate panels 6 and 7 and those of the opening/closing panels 8 and 9 in opening positions are in the same positions, respectively.
