When the operation lever 3 is swung by 17.9 °, the swinging angle β of the kicking member 4 becomes 23.2 °.

  As shown in FIG. 1 (B), in this sash window W, the protrusion of the lever can be eliminated and the width of the finding can be made small, so that the amount of the undrawn window can be reduced, and a sufficient opening width can be secured. At the same time, the problem that the packing of the screen door 13 does not come into contact with the summons of the shoji 14 is eliminated.

  Further, when the paper sliding door is closed from the open state, the protrusion 16a of the vertical frame has a portion corresponding to the attachment position of the pull handle 1 with the assist mechanism cut out in a predetermined range in the vertical direction (cut) Accidents in which a finger is caught between the notch 16b), the window frame 16 and the handle 1 can be avoided in advance.
