Abstract:
A vibration-isolating apparatus comprising:a first fixture; a second fixture spaced apart from the first fixture; a vibration-isolating base body interposed between and connecting together said first and second fixtures and formed of an elastic material having a rubber-like elasticity; a stopper rubber outwardly projecting from a second-fixture-side portion of the vibration-isolating base body so as to restrict a deformation of the vibration-isolating base body, the stopper ruber including a portion of a circumferential edge of the first fixture extended radially outward to form an extended fixture portion that is enclosed by the stopper rubber; a metal stopper fixed to the first fixture so as to surround the stopper rubber having a thickness greater than that of the extended fixture portion; the metal stopper including: a first contact surface in parallel with a compression-direction-facing surface of the stopper rubber in which direction the first and second fixtures are moved relatively toward each other; a second contact surface in parallel with a radial-direction-facing surface of the stopper rubber which radial direction is perpendicular to the compression direction; a third contact surface in parallel with a drawing-direction-facing surface of the stopper rubber in which direction the first and second fixtures are moved away from each other; a fourth contact surface in parallel with a circumferential direction-facing-surface of the stopper rubber; and the third contact surface being inclined at an angle in a range of 10Â°-50Â° with respect to a plane perpendicular to the compression and drawing directions, while a radially inner edge of the third contact surface projects radially inward from the second contact surface by not less than 10 mm and so as not to contact with the vibration-isolating base body.
