In the opening window biasing device 4, the gas spring 83 is used as a spring force generating source of the spring device 26, but instead or together with the coil spring 83 as a spring force generating source of the spring device 26. And the link arms 34a and 35a with the extension force based on the mechanical spring force of the coil spring.
The folding at a and 34b and 35b may be released, and instead of using the extension force of the gas spring 83 or the coil spring to release the folding, the contraction force thereof may be used.

Further, it is not necessary to dispose the open window biasing device 4 so as to push out the upper frame 17 of the window frame 15, but to push out the other vertical frames 18, 19 or the lower frame 20. In this case, the hinge mechanism 21 may be provided on the opposing vertical frame 19, 18 or the upper frame 17 side.

[0031]

According to the present invention, a uniform opening urging force can be applied to both sides of the sash, the cost can be prevented from increasing, and the sash can be smoothly opened and closed.
