Abstract
In a windowsill, when a sill attachment is pushed downwardly by the weight of a window pane, a pair of vertical plates of a sill member are pulled inwardly by engagement of downward hooks of a horizontal plate with upward hooks of vertical plates, thereby keeping the vertical plates from being deformed outwardly. Therefore, no gap would be formed between the vertical plates and side muntins, keeping rain water from penetrating into the windowsill.
