In a mounting structure for cylindrical packing for mounting a cylindrical packing on a fitting cylindrical portion of a housing, an outer circumferential surface of the fitting cylindrical portion includes: an intermediate outer surface, end outer surfaces formed into a narrower external shape than the intermediate outer surface, and a protruding strip extending axially on the end outer surface and formed such that a most protruding position from the end outer surface falls within a range of the external shape of the intermediate outer surface, and an inner circumferential surface of the cylindrical packing includes: an intermediate inner surface which is tightly attached and fitted to the intermediate outer surface, and end inner surfaces fitted to the end outer surfaces. An engagement groove extends on the end inner surfaces. |
