The lever assembly for a door lock comprises a door lock cylinder having a shank extended from each side of the door lock cylinder and two structure provided between the inside and outside lever and a door lock cylinder, respectively for resiliently returning and maintaining the levers in their horizontal positions. The returning and maintaining structure includes a spacer, a nut for fastening the spacer against the door lock cylinder, a mounting member for mounting a rotatable member, and a spring member cooperating with the rotatable structure and a retainer for holding the spring member, and a lever having a shaft fitted to the shank. The parts of the lever assembly are in turn fitted onto the shank in a cooperating relationship, thereby to resiliently return and maintain the lever in its original, horizontal position without tilting by using of the lever.
