Abstract
A tire vulcanizing mold includes a groove-shaped saw cut and a vent hole which are formed in a forming surface for forming a tire surface, the vent hole being opened in the forming surface so as to communicate with the saw cut, and a vent plug being fitted in the vent hole. The vent plug includes a circular-cylindrical housing interiorly including an air discharging path, a stem being inserted in the housing, and a valve body for opening and closing the air discharging path in an end portion closer to the forming surface. The housing has a top surface positioned closer to the forming surface such that the top surface is positioned closer to the forming surface than a groove bottom of the saw cut. The top surface is provided with a cutout by which the air discharging path and the saw cut are communicated with each other.
