PROBLEM TO BE SOLVED: To provide a revolving door apparatus capable of providing safety for all people in any situation. SOLUTION: This revolving door apparatus 100 comprises a rotating partition blade 10 having a center rotating body 11 rotated in one rotating direction about a rotating axis roughly aligned with the center axis of a cylindrical body 20, four inner blades 12 radially formed in plan view on the center rotating body 11, and a plurality of outer blade elements 13 formed by axially arranging on one inner blade 12 parallel with each other so as to close a clearance between the inner blades 12 and the side wall 21 of the cylindrical body 20 and reduced in weight. When a moving body is held between the side wall 21 of the cylindrical body 20 and the outer blade elements 13 of the rotating partition blade 10, the outer blade elements 13 are opened in a reverse rotating direction to form the clearance between the inner blade 12 and the side wall 21 of the cylindrical body 20.
