도 3내지 도 5를 참조하면, 본 발명에 따른 회동방지홈이 일체로 형성된 에어 서스펜션용 행거의 지지부재(12)(이하, "지지부재"라 칭함.)는 원반형으로 형성된 양측으로 제 1, 2돌출부(12b)(30)가 돌출된 형태이고, 그 중심에 제 2관통공(12a)과 회동방지홈(20)이 형성되어 있다.3 to 5, the support member 12 (hereinafter referred to as "support member") of the air suspension hanger formed integrally with the anti-rotation groove according to the present invention is formed in both sides of the disc first, The second protrusions 12b and 30 protrude from each other, and the second through hole 12a and the anti-rotation groove 20 are formed at the center thereof.

제 1돌출부(12b)는 상술한 행거(미도시) 양측에 동심(同心)하도록 형성된 제 1관통공(11a)에 삽입되도록 상기 제 1관통공(11a)의 내경과 거의 동일한 외경으로 형성되며, 이 제 1돌출부(12b)의 중심에는 제 2관통공(12a)이 형성되어 있다.The first protrusion 12b is formed to have an outer diameter substantially the same as the inner diameter of the first through hole 11a so as to be inserted into the first through hole 11a formed concentrically on both sides of the hanger (not shown). A second through hole 12a is formed at the center of the first protrusion 12b.

제 2관통공(12a)은 도시하지 않은 축볼트(13)의 관통이 용이하도록 약간 큰 내경으로 형성되는데, 이 제 1돌출부(12b)와 제 2관통공(12a)은 종래와 동일하다.The second through hole 12a is formed with a slightly larger inner diameter to facilitate the passage of the axial bolt 13 (not shown). The first protrusion 12b and the second through hole 12a are the same as before.

한편, 제 2관통공(12a)의 타측으로는 회동방지홈(20)이 형성되는데, 이 회동방지홈(20)은 축볼트(13)의 머리부(13a)가 삽입될 수 있도록 소정의 깊이를 갖는 육각형상으로 형성되어 있다.On the other hand, the other side of the second through hole (12a) is formed with the anti-rotation groove 20, the anti-rotation groove 20 is a predetermined depth so that the head portion (13a) of the shaft bolt 13 can be inserted. It is formed in the hexagon shape which has.

회동방지홈(20)이 소정깊이의 요홈으로 형성된 이유로는 행거(11)의 내부에서 행거빔(14)의 힌지부시(14a)가 축볼트(13)에 의해 결합될 때, 상기한 축볼트(13) 머리부(13a)의 지지가 용이하도록 하기 위한 것으로, 본 발명에 따른 지지부재(12)는 행거(11)의 어느 일측으로만 배치되고, 타측은 종래의 지지부재(SM), 즉, 평와셔가 구비되어도 된다.The reason why the anti-rotation groove 20 is formed as a recess of a predetermined depth is that when the hinge bush 14a of the hanger beam 14 is engaged by the shaft bolt 13 inside the hanger 11, the shaft bolt ( 13) To facilitate the support of the head 13a, the support member 12 according to the present invention is disposed only on one side of the hanger 11, the other side is a conventional support member (SM), that is, Flat washers may be provided.
