To provide a tire vulcanizing mold or the like, which can enhance an air discharge property in a cavity space and easily suppress poor appearance of a vulcanized tire.SOLUTION: There is provided a vulcanizing mold that comprises a tread molding ring for molding an outer surface of a tread portion of a tire. The tread molding ring comprises: a ground contact surface forming portion 103 for forming a ground contact surface on the tread portion; and a projecting portion 104 projecting radially inward from the ground contact surface forming portion 103 to form a groove-shaped recess in the tread portion. A through hole 106 is formed in the projecting portion 104, and a distance C between the through hole 106 and the ground contact surface forming portion 103 in the tire radial direction is 0.1 to 1.2 mm.SELECTED DRAWING: Figure 8
【課題】キャビティ空間内の空気の排出性を高め、加硫済タイヤの外観不良を容易に抑制できるタイヤ加硫金型等を提供する。【解決手段】タイヤ加硫金型は、タイヤのトレッド部の外面を成形するためのトレッド成形リングを備える。トレッド成形リングは、トレッド部に接地面を成形するための接地面形成部103と、トレッド部に溝状凹部を形成するために、接地面形成部103からタイヤ半径方向内側に突出する突出部104とを有する。突出部104には貫通孔106が形成され、貫通孔106と接地面形成部103とのタイヤ半径方向距離Cは、0.1〜1.2mmである。【選択図】図8
