Publication number: 20070216075Abstract: A construction of a fluid-filled vibration damping device provided with an air chamber for applying an air pressure capable of increasing the pressure of a fluid in a fluid chamber is realized advantageously in industry. An air chamber is formed between a cylindrical member and a bottom member forming a second mounting member, and a seal protrusion that is caused to fall easily to the inside of the air chamber is interposed between these elements. In the state in which the air chamber is formed, the cylindrical member and the bottom member are brought close to each other and lapped on each other, by which the volume of the air chamber is decreased by an amount corresponding to the approach amount of the elements and the volume amount of the seal protrusion entering into the air chamber due to falling, and thereby the internal pressure of the air chamber is increased.Type: ApplicationFiled: January 24, 2007Publication date: September 20, 2007Applicant: Tokai Rubber Industries, Ltd.Inventor: Yuichi Ogawa
