WINDOW

摘要

A window lockable even when the window is partially opened for ventilation is disclosed. The disclosed window comprises a window frame having a rail unit thereon; a window unit sliding on the window frame; an end cap which is mounted on the window unit to absorb impact of a collision between the window frame and the window unit when the window unit is opened and closed, and which includes a fixed plate fixed on the window unit and a rotatory plate rotatable from the fixed plate toward the bottom surface of the window frame; a locking protrusion protruding from one side of the rotatory plate; and a locking hole, in which the locking protrusion is inserted when the rotatory plate is rotated, provided on the bottom surface of the window frame and limiting movement of the window frame when the window frame is opened for ventilation.
