Fluid enclosure type vibration proof device
Document Type and Number:
Japanese Patent JP5941966
Kind Code:
B2
Abstract:
A fluid-filled vibration-damping device including first and second mounting members elastically connected by a main rubber elastic body and a fluid chamber whose wall is partially constituted by the main rubber elastic body. A sealing member attached to the second mounting member has a step part, and an attaching tube part and a sealing tube part on opposite sides of the step part. A press-fit projection is formed peripherally partially on at least one of an inner peripheral face of the attaching tube part and an outer peripheral face of the second mounting member, so as to secure press-fit the second mounting member inserted into the attaching tube part. A transmission prevention part is provided in the step part on a portion that transmits press-fit stress from the attaching tube part to the sealing tube part so as to reduce stress transmission.
