Therefore, in buildings such as houses, in order to improve the air conditioning effect, in order to reduce the energy loss in the air conditioning inside the building, to block the air in and out of the room, to prevent the heat in the room from leaking outside. , A highly airtight and highly insulated building with high indoor airtightness and heat insulation is used. In such a highly airtight and highly heat-insulated building, the entrance and exit of air inside and outside is blocked, so it is necessary to sufficiently ventilate the building.
Therefore, in order to ventilate a highly airtight and highly heat-insulated building, a central ventilation device that collectively ventilates a plurality of partitioned spaces such as living rooms in the building is used (see JP-A-11-344253). ).

However, when such a ventilation device is used, it costs a lot to install the ventilation device and consumes a lot of energy. Therefore, without using the ventilation device,
A building that can provide natural ventilation is proposed. In order to provide natural ventilation, it is necessary to ensure an inflow port that takes in the outside air, and if the passage through which the outside air passes is formed across multiple rooms, a door is required to secure the passage. An opening may be provided separately from the above. To this opening, a horizontal plate fixed at a predetermined angle is attached with a girder that is laid on top of one another at intervals so that air can be constantly ventilated.

[0004]

Since the horizontal plate is fixed at a predetermined angle in the louver attached to the opening, the opening cannot be closed, and there is a problem that the cooling / heating efficiency decreases during cooling / heating. there were. Therefore, the present inventor considered attaching a rotating window that can be opened and closed to this opening. However, since a general rotary window has only a stopper for supporting the rotary window when it is opened, it has a problem that the opening angle cannot be adjusted and the inflow of outside air cannot be adjusted.

An object of the present invention is to provide a rotating window whose opening angle can be adjusted.

[0006]

Only the spring may be biased. By doing so, there is no risk that the shaft portion 612 will come off from the bearing 620.
Further, only the shaft portion may be biased by a spring. Although the means for urging is a spring, it is not limited to this, and any means having elasticity may be used, and the engagement protrusion 613 may be formed of rubber or the like.

Further, although the spring 611 was attached to one side surface of the main body 610 of the attaching member 61, the shaft portion 612 or the engaging projection 613 itself was manually pushed from the other side surface of the main body 610 without being biased by the spring. The structure may be such that it can appear and disappear. With this configuration, the shaft portion 612 and the engaging projection 613 can be previously sunk into the other side surface of the main body when the rotary window main body 60 is attached, or the like.
Installation work becomes easier. Furthermore, in the above-described embodiment, the rotary window body 60 is detachable from the window frame 7, but the shaft portion 612 may be incorporated in the bearing 620 so that the shaft portion 612 does not come off from the bearing 620.
