PURPOSE: An apparatus for looking a door without using a key is provided to improve the convenience by employing an automatic locking unit that is rotated by hands. CONSTITUTION: A first locking unit(400) is coupled to a side of a door locking body and performs locking and unlocking functions through upward and downward movements. A rotational force delivery unit(200) is disposed on a side of the first locking unit(400) and applies force for moving the first locking unit(400) upwardly and downwardly. A second locking unit(300) is arranged on a side of the rotational force delivery unit(200) and performs a locking function after a door locking apparatus is locked in order to prevent an unlocking of the door locking apparatus by a key. An elastic guiding member(500) is coupled to another side of the rotational force delivery unit(200) to give an elastic force and maintains a constant sense with respect to the locking when the rotational force delivery unit(200) rotates. An automatic locking unit operates in connection with an upper portion of the rotational force delivery unit(200) to lock a door in response to rotation of the rotation force delivery unit(200) by hands.
