Liquid-sealed vibration damping device

A liquid-sealed vibration damping device comprising:

• a first mounting member that is mounted on a vibration source;
• a second mounting member as an outer cylindrical member that is mounted on a non-vibration source;
• and
• an insulator that is interposed between the first and second mounting members,
• wherein the second mounting member includes:
• a first frame in a cylindrical shape that is connected to a lower portion of the insulator;
• a second frame in a cylindrical shape that holds a partition member which is arranged below the insulator;
• and
• a connector that connects the first frame with the second frame,
• wherein the connector includes:
• engaging parts that are arranged on either one of the first and second frames;
• and
• elastic hook parts that are arranged on the other one of the first and second frames to engage with the engaging parts, and
• the first or second frame, which is arranged with the elastic hook parts, includes:
• a pair of main frame parts in a linear shape that faces each other;
• and
• a pair of side frame parts that connects ends of the main frame parts,
• wherein the elastic hook parts are arranged at intervals on each of the main frame parts in the circumferential direction of the said first or second frame, and among the elastic hook parts, the elastic hook parts arranged at the ends of the main frames have lower rigidity than those arranged at positions away from the ends.

• a low rigidity part having low rigidity;
• and
• a high rigidity part having high rigidity than the low rigidity part,
• wherein the elastic hook parts are arranged at intervals on the said first or second frame, which is arranged with the elastic hook parts, in the circumferential direction thereof, and the elastic hook parts arranged on the high rigidity part have lower rigidity than those arranged on the low rigidity part.
