PURPOSE: A hinge assembly for a Kimchi refrigerator is provided to prevent leakage or grease and possibility of aging by basically preventing the generation of noise even if time passes and to prevent the operational degradation of the hinge.CONSTITUTION: A pair of springs is installed inside a housing fixed to one side of an upper part of a refrigerator body. The cam portion comprises three inclined surfaces(41,41) initiated on the shaft and cam side contact bumps(42,42) in a protruded shape formed at the end of each inclined surfaces. A slide cam is contacted at a point with a cam side contact bump and a slide cam includes three cam sides(72,72) with an inverse inclined surface formed that is separated from the inclined surface. The cam portion comprises a central axis(C) and the first ledge(43,43) extended to the parallel direction with the central axis. The slide cam has the second ledge (73,73) where the first ledge is hung being extended to the parallel direction with the central axis. The cam side contact bumps contacted with the cam side at a point and simultaneously formed in a round to prevent the damage while thermo kinesis. The cam portion includes the first vertical end (44,44) connected to the cam side contact bumps in the vertical direction with the first ledge. The slide cam has the second vertical end(74,74) where the first ledge (44,44) is mounted. A bush is installed between a core and the cam shaft and the shaft penetrates the bush.COPYRIGHT KIPO 2013본 발명은 김치냉장고용 힌지 어셈블리에 관한 것으로서, 냉장고 본체(B)의 상부 일측에 고정되는 하우징(10)의 내부에 설치되는 한쌍의 스프링(20)(20)과 하우징(10)의 양측에 설치되는 커버(30)(30)와 스프링(20)(20)과 커버(30)(30) 사이에 상대회전 가능하게 설치되는 캠부(40)(40) 및 커버(20)(20)로부터 돌출되는 것으로서 냉장고 본체(B)를 개폐하는 도어(D)의 후단 양측에 고정되는 샤프트(50)(50)로 구성된 캠샤프트(60)(60)와 캠샤프트(60)(60)와 스프링(20)(20) 사이에 설치되어 캠부(40)와 캠접촉하면서 하우징(10) 내측에서 전후방으로만 슬라이딩 운동하는 슬라이드캠(70)(70)을 포함한다. 이때 캠부(40)(40)는, 외주면에 형성된 것으로서 샤프트(50)(50)에서 시작된 3개의 경사면(41)(41)과, 각각의 경사면(41)(41) 단부에 형성된 돌출된 형상의 캠면접촉돌기(42)(42)를 포함한다. 그리고 슬라이드캠(70)(70)은,
