Abstract
A vibration-isolating apparatus and a metal stopper having an excellent and lasting reliability comprises an outwardly projecting stopper rubber, and a metal stopper fixed to a first fixture so as to surround the stopper rubber. The metal stopper has a first contact surface in parallel with a compression-direction-facing surface of the stopper rubber, a second contact surface in parallel with a radial-direction-facing surface of the stopper rubber and a third contact surface in parallel with a drawing-direction-facing surface of the stopper rubber, and a fourth contact surface in parallel with a circumferential-direction-facing surface of the stopper rubber. The third contact surface inclines at an angle range of 10°-50° with respect to a plane perpendicular to the compression and drawing directions, while an inner edge of the third contact surface projects radially inward from the second contact surface by not less than 10 mm so as not to contact with the vibration-isolating base body.
