Vibration-isolating device

A vibration-isolating device, comprising:

• a vibration-isolating substrate formed of a rubber elastomer and having first, and second sides;
• a first metal fitting connected to said first side of said vibration-isolating substrate;
• a cylindrical or annular second metal fitting connected to said second side of said vibration-isolating substrate, said vibration-isolating substrate and said second metal fitting having substantially oval outer circumferential surfaces when viewed in an axial direction;
• a first stopper formed in connection with said first metal fitting;
• an outwardly projecting flange arranged in connection with said second metal fitting;
• and
• a stopper metal fitting comprising
• a caulking portion caulked and fastened with at least a part of said flange,
• a second stopper arranged close to and abutting said first stopper, and
• a cylinder portion including cutouts such that said caulking portion is not formed at said cutouts and said substrate and said flange are thereby exposed;
• wherein said stopper metal fitting is substantially cylindrical and said cutouts are provided at and around minor-axis ends of an oval in a vicinity of said flange;
• wherein said oval is in the shape of a racetrack, and said cutouts coincide with straight-line portions of the racetrack shape.
