Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a joining method of a rubber molding in which the rubber moldings can be joined in a sufficient accuracy at requested interval between them, and to provide a manufacturing method of an annular rubber gasket in which the joining method is used, thereby an annular rubber gasket of high dimensional accuracy can be manufactured efficiently without needing a large-scale apparatus, and annular rubber gaskets in which product in different specifications and sizes can be also manufactured. SOLUTION: The joining method of a rubber molding which joins two or more rubber moldings 10 preformed by a vulcanizing molding of a rubber, includes: arranging a section 10a to be joined in the rubber molding 10 to be joined in a predetermined mold 1 at a predetermined interval D through a positioning means 4; loading an unvulcanized rubber G into the cavity 50 formed at the interval D and the mold 1; and vulcanizing-molding the unvulcanized rubber G to join the sections 10a and 10a.
