Japanese Patent JP3632690

B2

The present invention provides a vibration isolator having a stopper function in the up-and-down direction and the fore-and-aft and lateral direction square to the axis, being able to prevent water intruded into the top surface of a flange from being accumulated, and allowing the dies axially to be parted. As means thereof, a cylindrical body fitting (1) and an upper side attachment fitting (2) having a flange (2a) for the stopper are connected via a vibration isolating substrate (3), a cylindrical stopper fitting (9) extending outside the vibration isolating substrate up to above the flange is fixed to the body fitting, being folded inside so that the upper extremity portion of the stopper fitting (9) lies above the flange, a stopper rubber (10) is provided on the top surface and outer circumferential portion of the flange (2a), the flange (2a) abuts the stopper fitting through the stopper rubber when the upper side attachment fitting (2) moves largely, a notch groove (11) for drainage continuous from the top surface to the outer circumferential portion, desirably having the depth substantially equal to or a little shallower than the thickness of the stopper rubber is provided at least one place circumferencially on the stopper rubber (10).
