Abstract
Description
상기 환상부재의 상기 직경방향부와 상기 축방향부에 걸쳐 설치되어, 상기 환상구멍의 주면에 밀봉접촉하는 밀봉 립을 가진 밀봉부재 본체를 갖추어,
상기 환상부재의 축방향 한쪽 편과 다른 쪽 편을 밀봉하는 밀봉장치에 있어서,
상기 축방향부는, 상기 직경방향부와는 반대쪽의 제1축방향과, 이 제1축방향부보다 두께가 얇고 상기 직경방향부에 이어지는 제2축방향부를 구비하고,
상기 밀봉 립은, 상기 직경방향과 제2축방향과의 각부 부근에 설치되어 있고,
상기 밀봉부재 본체는, 상기 밀봉 립의 근본으로부터, 제1축방향부와 제2축방향부 사이의 계단부에 이르는 위치까지 제2축방향부를 피복하는 부분을 가진 것을 특징으로 한다.
