PROBLEM TO BE SOLVED: To provide an opening/closing structure of a hive gate and ventilation windows of a bee hive in which the ventilation in a hive can thoroughly be performed by widely providing an opening of the ventilation windows, and the opening/closing work of the ventilation windows and the hive gate can also be performed simply.SOLUTION: An opening/closing structure of ventilation windows 22 and a hive gate 23 of a bee hive is provided at a side plate of the bee hive. The opening/closing structure of the ventilation windows 22 and the hive gate 23 includes: a front plate 2 and a back plate 5 provided with the multiple ventilation windows 22 and one hive gate 23 in the same position, respectively； a slide member 34 sandwiched between the front plate 2 and the back plate 5, and provided in a certain direction in a reciprocating manner； and a screen window plate 4 for sealing the openings of the ventilation windows 22 in a ventilating manner. When the positions of the ventilation windows 22 and the ventilation opening 32 are brought into communication with each other by moving the slide member 34, the ventilation windows 22 are opened and the hive gate 23 is closed simultaneously. When the positions of the ventilation windows 22 and the ventilation opening 32 are alternated, the ventilation windows 22 are closed and the hive gate 23 is opened simultaneously.SELECTED DRAWING: Figure 1
