Vibration damping device

A method of manufacturing a vibration damping device including a first attachment member and a second attachment member connected by a main rubber elastic body, the method comprising:

• preparing a main rubber outer member including a first tubular part to be fastened to an outer peripheral end of the main rubber elastic body, and a drawing fitting including a second tubular part to be attached externally about the first tubular part of the main rubber outer member;
• inserting the first tubular part into the second tubular part and attaching the drawing fitting to the main rubber outer member;
• and
• performing a drawing operation on the second tubular part to impart tapered contours at a portion of the second tubular part that is overlapped on the first tubular part thereby forming a tapered part on the second tubular part, the tapered part decreasing in diameter in a direction of dislodgment that is opposite to a direction of insertion of the first tubular part into the second tubular part, while fitting and fixing the tapered part to an outer circumferential surface of the first tubular part to position the main rubber outer member and the drawing fitting with respect to each other in an axial direction, wherein
• the first tubular part of the main rubber outer member includes a first outer flange projecting radially outward at an upper axial end of the first tubular part,
• the first tubular part of the main rubber outer member includes a first inner flange projecting radially inward at a lower axial end of the first tubular part,
• the first tubular part overall from the lower end to an upper end serves as the tapered part that decreases in diameter toward a top,
• the second tubular part of the drawing fitting includes a second outer flange projecting radially outward at the upper axial end of the second tubular part, and
• a caulking fitting is provided such that the first outer flange and the second outer flange that are overlapped on each other in a state of contact are fixed by caulking by the caulking fitting.
