A safety window for a veranda is provided to prevent trespass by moving a window for a veranda inward to be locked when pressure is applied from the outside. A safety window for a veranda uses the method of a locking device fixing to a security glass sash of the inside and the entire frame of a window for a veranda, and pushes a sash to stick the palm when opening a door from the outside. When external pressure is applied, the window for a veranda moves toward the inside automatically and a locking device mounted to a window frame for a veranda is coupled with the window for a veranda to keep the door not to move. |
