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.
