PROBLEM TO BE SOLVED: To provide a molding die that firmly supports semi-tubular bodies being apt to fall down and doest not greatly affect spring characteristics of a vibration control device, and a vibration control device having excellent spring characteristics. SOLUTION: The molding die is used for vulcanization molding of a vibration control device in which each semi-tubular body 5 having a pair of arcuate end parts 5a, 5a each having an almost semi-arcuate shape is embedded into a rubber elastic body 3. A plurality of support pins 14 for holding each arcuate end part 5a of each semi-tubular body 5 are provided in a region that partitions the lower face of a cavity of a lower die 10b so as to hold regions of two parts on both sides excluding a prescribed region including the center of each arcuate end part 5a. Each support pin 14 has a pair of holding pieces 14a, 14a while each protrusion part 14b is formed at each part, facing each other, of the holding pieces 14a. COPYRIGHT: (C)2009,JPO&INPIT |
