Abstract:
A two chamber liquid enclosing type vibration isolating mount, comprising: in a sealed state, a cylindrical metal; a fixing metal; a vibration isolating base member made of rubber and coupling the cylindrical metal and the fixing metal; a diaphragm made of a first rubber membrane and arranged at an opening of the cylindrical metal opposing to the vibration isolating base member; a partition member arranged inside the diaphragm and dividing a space between the vibration isolating member and the diaphragm into two liquid chambers communicating with each other through an orifice path,wherein said partition member comprises an annular rigid portion for forming said orifice path along an outer periphery thereof and a second rubber membrane attached to the inside of said rigid portion and defining said two liquid chambers, and the thickness of a portion of said second rubber membrane close to an attached portion thereof is made thinner than an inner part of said second rubber membrane, an inner surface of said vibration isolating base member including a first stepped surface formed along a periphery thereof, the outer periphery of said partition member including a second stepped surface, said first stepped surface being held in contact with the second stepped surface of said partition member.
