Abstract
A tire vulcanizing mold is disclosed capable of accurately providing a clearance, from which air existing between a green tire and a side mold is released, on a side shaping surface and thereby preventing shaping defect. The tire vulcanizing mold includes an upper and lower pair of side molds having side shaping surfaces, each of which shapes a sidewall of a tire. Each of the side molds includes a side mold main body, plural pieces, and a clearance provided between the side mold main body and each of the pieces. The side mold main body includes plural recesses, each of which is closed in a tire circumferential direction and a tire radial direction and is opened to a side shaping surface, at spaced intervals in the tire circumferential direction. Each of the pieces is fitted into the recess and forms the side shaping surface with the side mold main body.
