An annular rubber-like elastic packing body having a seal lip that slides on the shaft is fitted on the inner circumferential side of the packing body, and an inward flange that comes into contact with the atmosphere-side end surface of the packing body is provided in the housing. In a reciprocating packing in which the pressure acting on the sealed fluid side end face is supported by an inward flange, the sealed fluid side end face of the packing body is gradually moved from the outer diameter side toward the inner diameter side with respect to an orthogonal plane perpendicular to the axis. For reciprocating motion, the tapered surface is inclined toward the atmosphere in the axial direction, and a gap is formed in the axial direction at the outer diameter side end of the contact portion between the inward flange and the packing body. Patsukin.
