PROBLEM TO BE SOLVED: To provide a mount structure for seal packing capable of easily mounting it and carrying out the work efficiently. SOLUTION: A mount structure for seal packing to be interposed between the outer cylindrical body having a circular inner peripheral surface and an inner cylindrical body having a circular outer peripheral surface installed on the same axis inside the outer cylindrical body forms a peripheral surface in taper at the seal base 11 when fitting and fixing the seal base portion 11 of seal packing on the outer peripheral surface of the inner cylindrical body, and a taper surface linking to the taper inner peripheral surface is formed on the outer peripheral surface of the inner cylindrical body. Also, in adjacency to the rear end portion of seal packing fitted and fixed to the outer peripheral surface of the inner cylindrical body, a ring for preventing pull-out is attached. In addition, a rubber seal packing is heated and thermally expanded in radium direction, and its inner diameter is enlarged and fitted to the outer peripheral surface of the inner cylindrical body and fixed after shrinkage. |
