As this latch mechanism, for example, as disclosed in Patent Document 1, a latch 35 provided on a door-to-door frame 12 disposed to face the screen mounting frame 10, and the front surface of the screen mounting frame 10 It is usual to consist of the hanger 39 provided in the part. When the screen 2 is expanded, the engaging portion 36 of the latch 35 enters the opening 38 of the hanger 39 by sliding the screen mounting frame portion 10 to the door stop frame 12, and the tip thereof is the opening 38. By being hooked on the hanger 39 at the edge, a locked state is established.

  By the way, in order to hold the screen in the locked state, if the operator is on one side of the screen, for example, the room interior side of the screen, and operates the screen mounting frame 10 toward the door stop frame 12, the screen mounting frame 10 Is applied not only to the door-to-door frame 12 side but also to the screen-mounting frame portion 10 on the other side. The component force in that direction will act. As a result, the screen mounting frame portion 10 is guided by the upper and lower slide guide frame portions 15 and 16 and restricted in movement, so that there is no extreme displacement movement, but to some extent between the slide guide frame portions 15 and 16. Therefore, the screen mounting frame portion 10 is biased to the other surface side by at least the gap.

  Therefore, in the horizontal screen device as disclosed in Patent Document 1, when the screen 2 is moved in the extending direction to be in the locked state, the screen mounting frame 10 is a surface on which the operator of the screen 2 is located. As a result, the latch 35 and the hanger 39 are displaced in the direction of the front and back surfaces of the screen, and the latch 35 is not easily hooked. If the screen mounting frame 10 is pulled toward the front side (the operator side) and slid and moved while considering the position of the latch 35 and the opening 38 of the hanger 39, the above-mentioned problem is solved. There are difficulties in getting used to the movement.
