Each of the inner and outer rubber layers are obtained by vulcanizing a rubber composition including a rubber material selected from the group consisting of a halogenated butyl rubber material, and a blend of a halogenated butyl rubber material and a butyl rubber material. The vulcanized rubber includes a filler having a layered crystal structure and is vulcanized with one of a peroxide vulcanizing agent and a resin vulcanizing agent.
