PROBLEM TO BE SOLVED: To provide a vibration control device for suppressing the transmission of hammering sounds generated by the impact of a distribution control plate colliding with a first partition member and a second partition member, as abnormal noises to the outside of the device. SOLUTION: An orifice forming part 56 has: an orifice groove 58 formed opening along the axial direction to the side of an orifice cover part 64; and a pair of bulkhead portions 134, 136 formed extending from the bottom face of the orifice groove 58 to the opening end. Thus, the rigidity of a partition fitting 46 is increased along the axial direction of the orifice forming part 56. When the orifice forming part 56 is subjected to great constraining force (compressing load) along the axial direction of a stepped part 28 and a caulked part 32 of an outer cylinder fitting 12, the orifice forming part 56 is prevented from being plastically deformed along the axial direction. Thus, the constraining force of the stepped part 28 and the caulked part 32 on the orifice forming part 56 and the orifice cover part 64, is sufficiently increased. COPYRIGHT: (C)2008,JPO&INPIT |
