Claims

[Scope of utility model registration request]

A first pressure-receiving surface is composed of a first contact surface on the outer diameter side of the upper and lower side plates forming the sidewall portion of the tire and a contact surface on the inner diameter side of the segment arranged on the outer diameter side of the side plate. At the same time, a contact surface on the inner diameter side of the sector that is arranged inside the segment and constitutes the circumferential index position of the tire shoulder portion, and a second contact surface on the outer diameter side of the upper and lower side plates. A tire mold vulcanizing device characterized in that a second pressure receiving surface is configured with.
