Japanese Utility Model Publication No. 60-146165

  The conventional structure is to prevent the screen door from rising from the sash frame by preventing the screen door from rising, but it is in a restricted state due to loosening or forgetting to tighten due to secular change of the screw that attached the sash frame to the device body. May not be held, and may move up and down easily with a moving operation, etc. Also, even if the fixed (attached) state with the screw is as designed, when exposed to strong winds, the upper side will Since the upper frame is in a state where the lower side is respectively fixed to the lower frame, strong wind acts on the middle part in the vertical direction, and it may protrude and protrude in the outdoor direction. Thus, it cannot cope with the detachment due to the deformation of the screen door.

  The present invention has been devised to provide an apparatus capable of reliably preventing the screen door from coming off (dropping off) from the sash frame with a simple structure, paying attention to the drawbacks of such a conventional example.

  In the sliding door sash in which the screen door provided with the door wheel that rolls along the guide rail provided in the sash lower frame is fastened to the sash frame, a release prevention material is attached to the sash frame, the release prevention material, As a basic means, the basic means that it is placed in the indoor and outdoor direction on the outdoor side with respect to the screen door lower arm when the screen door upper arm is brought into contact with the lower end of the sash upper frame by the sword operation, By further adding a point where the separation gap between the anti-separation material and the outdoor end surface of the screen door armpit is narrower than the clearance gap between the door carriage or guide rail and the indoor end surface of the screen door armpit, it is more reliably prevented from coming off. Expect an effect.

  The relationship between the separation gaps means that the anti-separation material regulates the outdoor movement of the screen door armor when the engagement gap between the door carriage and the guide rail is interrupted, and expects the anti-screening effect of the screen door. .

  According to the present invention, it is possible to provide a suitable device as a stopper that has a simple structure and copes with falling off of a sash frame due to deformation of a screen door by being exposed to a strong wind as well as in a normal state.
