Abstract
A vulcanizing mold manufacturing method, and a tire vulcanizing mold are disclosed. Tubular bodies each formed by oppositely arranging the inner peripheral surfaces of both end portions of a plate-shaped body are each arranged so that the gap between both opposite end portions thereof is narrowed and that the tips of both end portions come in contact with the surface of the plaster mold, by inserting and fitting both opposite end portions into a fitting portion of a plate-shaped metal fitting protruding from the surface of the plaster mold. Molten metal is poured over the surface of the plaster mold to embed the tubular body in a mold while exposing the tips of both opposite end portions at the tire molding surface of the mold. The metal fitting is removed from the mold, so that a mold having a small gap between both opposite end portions is manufactured.
