PROBLEM TO BE SOLVED: To provide a glass door unit and a glass door unit, which are equipped with a simple and inexpensive mechanism for making air flow into an indoor side from an outdoor side when the indoor side of a bathroom etc. is brought into negative pressure, that is, lower pressure than its outdoor side. SOLUTION: A vent hole 13 is provided in the door panel 11 of the glass door 10 in such a manner as to be concealed with a handle 12. A flap 21 for opening/closing the vent hole 13 is installed inside the vent hole 13. When a bathroom side is brought into negative pressure by the operation of a ventilating fan, the negative pressure makes the flap 21 swung to the bathroom side, so as to open the vent hole 13. A bathroom-side surface of the flap 21 is inclined to get closer to the bathroom side toward a lower end side. COPYRIGHT: (C)2009,JPO&INPIT
