To provide a seal mechanism for piping, which can fix the piping to an arbitrary position according to an eccentric between a central axis of the piping and a central axis of a pipe conduit on a wall member and improve pressure resistance for sealing a clearance between the piping penetrating the pipe conduit on the wall member and the wall member.
The seal mechanism for piping 100 includes a first closing member 1, a second closing member 2, and fixing means 3. The second closing member 2 has an outer plate member 21 as a plate with a larger outer contour than those of a first inner plate member 11 and a second inner plate member 12, and can be fixed to the pipe conduit 60. When viewed from a direction in parallel with an extending direction of the piping 5, the fixing means 3 fixes the position of the first closing member 1 guided movably in a radial direction of a first penetration hole O1 relative to the second closing member 2 while outer peripheries of the first inner plate member 11 and the second inner plate member 12 overlap with the outer plate member 21, and seals a space between the second inner plate member 12 and the outer plate member 21.
