Abstract

본 발명은 로커아암의 아암축받이부의 축받이 구멍의 축받이 구멍축심선을 캠축의 캠축심선에 대하여 경사지게 하게끔 로커아암을 경사지게 하는 로커축 끼워넣는 구멍이 형성된 로커아암 경사용 스페이서를 아암축받이부의 축받이 구멍에 설치하고 있는 구성으로 되어있고 또한 로커축 외주에 로커아암을 걸어맞추는 구멍 걸어맞춤부를 설치하여 캠축의 중심축선에 대해서 구멍걸어맞춤부에 끼워 넣어지는 로커아암의 축받이 구멍의 중심축선을 경사지도록 해서 로커아암을 엔진에 배치하도록 구멍 걸어맞춤부의 중심축선을 로커축의 중심축선에 대해서 경사지워서 설치되어 있다.
