摘要：
The invention relates to a vent plug for a tire vulcanization mold used for a vent hole of the mold, the tire vulcanization mold, and a manufacturing method for the tire using the mold. The vent plug includes a plug holder with a hollow ventilation portion and a plug head within the ventilation portion. The plug holder includes a tapered seat portion, an inside diameter of which becomes smaller toward a mold rear side, and a cylinder portion located at the mold rear side of the seat portion. The plug head includes a tapered head portion, an outer diameter of which becomes smaller toward the mold rear side, a base body portion located at the mold rear side of the head portion, and a slit portion communicating with the ventilation portion from an upper end face of the plug head.
