Fluid-filled elastic mount

A fluid-filled elastic mount comprising:

• a first mounting metal member;
• a rubber elastic block having two end sides, said rubber elastic block being secured on one end side of said two end sides to said first mounting metal member and having a cavity on the other end side of said two end sides;
• a cylindrical metal member which is secured to an outer periphery of said other end side of said rubber elastic block;
• a bottomed cylindrical second mounting metal member which is secured to an outer periphery of said cylindrical metal member to define with said cavity of said rubber elastic block a closed space;
• a diaphragm, a peripheral end portion of which is retained by one of said second mounting metal member and a cylindrical retaining metal member fitted to said rubber elastic block to divide said closed space into a fluid-filled chamber filled with a fluid, and an air chamber filled with air;
• and
• a partition member which partitions said fluid-filled chamber into a main chamber and an auxiliary chamber, and defines with said rubber elastic block an orifice passage interconnected with said main chamber and said auxiliary chamber, said fluid inside said fluid-filled chamber being pressurized through the increase of the internal pressure of said air chamber and the deformation of said diaphragm due to the forcibly fitting of said second mounting metal member on said cylindrical metal member.
