On the other hand, when the number of partition panels is two, the two first and second partition panels are fixed to the spindle at an angular interval of 180 degrees. The entrance / exit portion is brought into communication with the panel rotating in the entrance / exit portion. Therefore, conventionally, as shown in FIG. 4, arc-shaped arc panels 10 a and 11 a are extended toward the front side in the rotational direction of the door body at the outer diameter side edges of the first and second partition panels 10 and 11. In the case where the first and second partition panels 10 and 11 rotate at the entrance / exit portions 2b and 2c of the cylindrical wall body 2, the arc panels 10a and 11a close the entrance / exit portions 2b and 2c. The indoor / outdoor communication state is blocked. In this case, the lengths of the circular arc panels 10a and 11a in the circumferential direction are set to be substantially the same as the circumferential lengths of the entrance / exit portions 2b and 2c, but the entrance / exit portions 2b and 2c are connected to four partition panels. When the angle range of 90 degrees is set as in the case of providing, as shown by the two-dot chain line, the length in the circumferential direction of the circular arc panels 12a and 13a provided in the partition panels 12 and 13 is increased, so In order to give anxiety, it is proposed to set the angle range to 60 degrees.
By the way, when providing either the door body provided with four partition panels and the door body provided with two partition panels in the cylindrical wall body set to the same diameter, it is provided between adjacent partition panels. The area of the compartment formed is larger when a door body provided with two partition panels is used. For this reason, although the door body provided with two partition panels can increase the number of persons accommodated in each compartment, as described above, the opening width of the doorway is narrowed (shortened) to an angular range of 60 degrees. There is a problem that the person entering the compartment at each doorway and the person exiting are crowded.

As an improvement measure, the arc panel of the door body is abolished to secure a wide (large) opening width with the opening width of the entrance / exit part being an angle range of 90 degrees, and an opening / closing panel is provided at the entrance / exit part of the cylindrical wall body. The door body has been proposed to open and close the open / close panel in accordance with the operation of rotating the doorway to prevent the doorway indoors and outdoors from communicating.
