  • Fluid-filled type vibration damping device and manufacturing method thereof
    Patent number: 8936235
    Abstract: A fluid-filled type vibration damping device including a base component and a tubular mating component. The tubular mating component is externally fitted onto the base component by means of a diameter-constricting caulking with a sealing rubber clasped therebetween so as to constitute a mate-fastened portion. The tubular mating component extends axially outward beyond a sealed section of the mate-fastened portion so as to provide a caulking tube portion. A diametrical position of the tubular mating component at the sealed section is determined by contact of the caulking tube portion against an outside peripheral face of a positioning projection provided on the base component so as to define a diametrical positioning portion. The caulking tube portion is constricted in diameter and held in engagement with an axial edge portion of the positioning projection so as to form an axial positioning portion.
