Claims

[Scope of utility model registration request]

A pair of door pockets, a pair of door bodies arranged in an entrance/exit formed between these door pockets and curved in an arc shape, and a pair of door roller mechanisms that support these door bodies and can run in forward and reverse directions, respectively. , a circular door opening/closing device which is arranged on the indoor side and the outdoor side with a windbreak room separated, and is equipped with a drive device that drives each door body in an arc shape along the entrance or exit so as to draw or approach each other. Each door body is arranged uniformly offset only on the outdoor side with respect to each corresponding door compartment, and the offset direction is determined through a rotating shaft fixed to the drawing side end of each door body. It is connected to the corresponding door roller mechanism so that it can rotate horizontally, and
Either one of a perforated member having a hole and a protruding member that is fitted into and removed from the hole is provided at the drawing side end of each of the door bodies, and the other is provided at the end of each of the door roller mechanisms. The perforated member is provided with an engagement mechanism in the hole of the member that elastically biases the protruding member in the axial direction of the protruding member. A circular door opening/closing device characterized in that a direction of removal and removal is set to be perpendicular to a straight line connecting the engagement position of the two and the rotation shaft.
