The present invention relates to an automatic locking device for a window. The automatic locking device for the window is automatically locked or unlocked by a handle when the window is opened or closed by installing a locking keeper (100) and a locking unit (200) to face each other in a window frame and the window. The locking unit (200) includes: a rotor (30) which has a second operation protrusion (32) protruding at the bottom and a first operation protrusion (31) elastically rotated on one side and is rotated by the handle in the inner center of a housing (20); a first and a second locking operation unit (40, 40') which are installed on both inner sides of the housing (20) by shafts, are elastically rotated to be individually separated outwards, and have, at the front, locking grooves (43, 43') in which a locking protrusion (10) is inserted and a hanging protrusion (42, 42') which is hung on the locking protrusion (10); and an engaged operation unit (50) horizontally and elastically moving by the second operation protrusion (32) of the rotor in the lower part of the second locking operation unit (40'). The first locking operation unit (40) has a locking support groove (44) in the lower part and locks or unlocks the window as the first operation protrusion (31) of the rotor is elastically inserted in or separated from the locking support groove. The second locking operation unit (40') has an operation protrusion unit (46) in the lower part and locks or unlocks the window by being elastically supported on an upper surface (51) of the engaged operation unit or by being elastically inserted into a central operation groove (52). Therefore, the automatic device for the window is characterized by having excellent reliability of opening and closing operations with a simple structure, by being conveniently assembled or disassembled, and minimizing failure, damage, and malfunction of components. |
