PROBLEM TO BE SOLVED: To provide an apparatus for producing a roller good in vibration precision the cost of which can be reduced by simplifying the structure of a cylindrical mold which tends to be abraded and deteriorated as compared with a core metal holding member into the type of a cartridge. SOLUTION: In the apparatus composed of the cylindrical mold 1 into which a core metal 2 is inserted, core metal holding members 3, 4 for holding both ends of the core metal 2, and a base mold 10 which covers the peripheral surface of the cylindrical mold 1, the opening end part space of the mold 1 and the angle engagement bodies 3a, 4a of the holding members 3, 4 are tapered and engaged compensatively, and a means for bonding the members 3, 4 to both ends of the base mold 10 is provided. |
