The present invention relates to an acetabular cup for an artificial hip joint, and more specifically, to an acetabular cup for (revision) of an artificial hip joint, in which fixing unit insertion holes into which fixing units for fixing an acetabular cup for an artificial hip joint inside the acetabulum of the pelvis are inserted are formed in the acetabular cup in directions of the pubis and the ischium of the pelvis as well as in a direction of the ilium of the pelvis, so that, particularly, even when the acetabular cup previously operated inside the acetabulum is removed and acetabular revision is performed, the revised acetabular cup can be strongly fixed inside the acetabulum； among first to third fixing unit insertion holes, second and third fixing unit insertion holes formed in the acetabular cup, into which fixing units can be respectively inserted and combined in the directions of pubis and ischium of the pelvis in the acetabular cup, are formed within a range of 30-60 degrees in the left and right from a central axis which passes a central site of a plurality of first fixing unit insertion holes and the center of an outer diameter of the acetabular cup and within a height of 13-35 degrees from the bottom of the acetabular cup based on the center of the outer diameter of the acetabular cup, so that the fixing units are stably inserted and combined into the pubis and the ischium of the pelvis； and the acetabular cup can be strongly fixed inside the acetabulum by further including at least one fixing flange which protrudes outwardly from an outer surface of the acetabular cup in the direction of ilium of the pelvis, and at least one hook part which protrudes from the bottom of the acetabular cup and is bent, and can be caught on a bone connecting the pubis and the ischium.본 발명은 인공고관절용 비구컵에 관한 것으로, 보다 상세하게는 인공고관절용 비구컵을 골반의 비구 내에 고정시키기 위한 고정수단이 삽입되는 고정수단삽입공이 비구컵에서 골반의 장골방향은 물론 골반의 치골 및 좌골 방향으로도 형성되도록 하여 특히, 비구 내에 기 시술된 비구컵을 제거하고 비구컵을 재치환하여 시술하는 경우에도 재치환되는 비구컵
