Abstract: To provide a vibration isolation unit capable of reducing the number of parts, man-hour and material cost, and suppressing the product cost. One side of a stopper rubber member continues to the outer edge of a diaphragm. Accordingly, because they can be vulcanizingly molded simultaneously, the number of parts can be reduced. Also, because the diaphragm is attached to an outer tube member, the stopper rubber member also can be fixed simultaneously, and therefore the man-hour can be reduced. Further, because one side of the stopper rubber member continues to the outer edge of the diaphragm, overlapping of them in an axial view can be avoided, and a rubber material can be used efficiently. Thus, the number of parts, man-hour and material cost can be reduced and the product cost of the overall vibration isolation unit can be suppressed.
