摘要

A metallic mold for vulcanizing molding of cogged V-belt with unvulcanized belt material, including a lower mold having a gentle back curve in lengthwise direction thereof and an upper mold having a cogged surface with cog peak parts and cog trough parts arranged alternately. The upper mold is so designed that cog peak parts in the specific range at both end portions thereof are narrower than those at the other part but both are the same in height in lengthwise direction.
