The present invention relates to a door latch assembly including: a case (100) composed of left and right division members and having provision holes (101) formed at both side surfaces thereof, and having an opening part (103), which is formed at one side end part and has a cover (102) coupled thereto; a hub (200) rotatably provided in the provision holes (101); a locking member (300) for setting the locking of a door by controlling the rotation operation of the hub (200); a sliding member (400) elastically provided by a coil spring (401) so as to slide by the rotation of the hub (200); and a latch bolt (500) provided to enter and exit the opening part (103) for controlling the opening and closing of the door. The present invention further includes an operation rod (600) for sliding together with the sliding member (400) and a latch bolt (500) enabled to slide and rotate, thereby achieving purposes of stably opening and closing the door even with small force by improving the operability of the latch bolt when opening the door and, simultaneously, suppressing noise in the process of opening or closing the door. |
