PROBLEM TO BE SOLVED: To form a connection port of an external air pipe unit for an air passage giving an influence of air pressure by a simple structure and an excellent quality of manufacture, in an air pressure controlled vibration damping device. SOLUTION: A connection port of an external air pipe unit 92 in an air passage 84, positioned to be received in a recessed part 86 provided in a passage forming member 40, in a form without protruding from a peripheral surface of the passage forming member 40 serving as a fitting surface relating to a cylindrical part 34 of a second mounting member 14, is constituted by a pipe member 88 integrally formed to be protruded. In this way, necessity for separately forming the connection port relating to the external air pipe unit 92 assembled in the passage forming member 40 can be eliminated. |
