[PROBLEMS] To provide a doorway device that allows a large number of people to pass through it while maintaining a windshield effect and in which safety passersby is increased. [MEANS FOR SOLVING THE PROBLEMS] This doorway device comprises flat surface panels (14a) to (14c) which circulatingly move through an inlet passage (12) and an outlet passage (10) formed in a booth (6) positioned at the front of a building (2) so that the inlet passage (12) and the outlet passage (10) are brought into a non-communicated state. The flat surface panels (14a) to (14c) are slid parallel with each other in the inlet passage (12) and the outlet passage (14) and laterally slid from one passage to the other at the openings of the inlet passage (12) and the outlet passage (10) to circulatingly move in a square pattern.
