SEALING MEMBER AND MASU
To provide a sealing member that reduces insertion force when inserting piping.SOLUTION: A sealing member 50A for sealing between a masu body part having an opening formed on an outer surface and piping arranged in the opening of the masu body part comprises: an annular member 51A; a large-diameter part 52A that is provided in a portion of one side D1 along a central axis line O3 of the annular member on an inner peripheral surface of the annular member; a small-diameter part 53A that is provided in the portion of the other side D2 closer to the central axis line than the large diameter part and located along the central axis line on the inner peripheral surface of the annular member, and has an inner diameter smaller than that of the large-diameter part; and a stepped part 54A that is formed so as to be continuous between the large-diameter part and the small-diameter part.SELECTED DRAWING: Figure 6
【課題】配管を挿入するときの挿入力を低減させた封止部材を提供する。【解決手段】外面に開口が形成された升本体部と、升本体部の開口に配置される配管と、の間を封止する封止部材５０Ａであって、環状部材５１Ａと、環状部材の内周面における、環状部材の中心軸線Ｏ３に沿う一方側Ｄ１の部分に設けられた大径部５２Ａと、環状部材の内周面における、大径部よりも中心軸線に沿う他方側Ｄ２の部分に設けられ、大径部よりも内径が小さい小径部５３Ａと、大径部と小径部との間に連なるように形成された段差部５４Ａと、を備える。【選択図】図６
