It can be prevented from flowing into the space Pa. Therefore, it is possible to prevent rainwater from flowing into the hollow hollow portion 32 or into the indoor side from the gap around the support shaft 37 of the handle 30. Further, even if outside air or rainwater slightly flows into the internal pressure space Pa partitioned by the slider 34 and the first hermetic piece 40 or the internal pressure space P of the hollow hollow portion 32, since both are internal pressures, the external air Rainwater and the like can be prevented from being drawn in.

As described above, according to the vertical sliding window 1 according to the first embodiment, the internal pressure space Pa and the hollow hollow space partitioned by the slider 34 of the hollow frame portion 33 in which the distal end portion 30c of the handle 30 is accommodated and the first airtight piece 40 are provided. Since the internal pressure space P of the portion 32 can be maintained almost at the indoor pressure, it is possible to prevent external air, rainwater, and the like from leaking or flowing into the indoor side from the outside through the gap around the swingable handle 30. Can be blocked.
Further, even when rainwater or the like leaks into the internal pressure space Pa partitioned by the slider 34 and the first hermetic piece 40, the internal pressure is maintained, so that it can be prevented from being drawn indoors.

  Note that the vertical sliding window 1 according to the present invention is not limited to the above-described embodiment, and can be appropriately changed or replaced without departing from the spirit of the present invention.
