An exhaust pipe supporting device, with which the absolute spring rate in a special frequency range can be reduced, comprises a first holding portion a second holding portion a pair of side wall portions connecting on both sides of both holding portions and a central vibration damping portion interposed at an intermediate position between the first and second holding portions wherein the central vibration damping portion comprises a mass portion and a pair of connecting portions which connect two sides of the mass portion to the side wall portions the mass portion is formed to have larger mass than that of the connecting portions and the connecting portions may be provided with concave portions depressed in the longitudinal direction on the connecting portion the size T of the connecting portion in the longitudinal direction thus being set smaller than the size T of the side wall portion in the longitudinal direction.

Exhaust pipe supporting device

The invention provides an antivibration device lightweight and excellent in heat interception, wherein a top opening of a main body fitting ( ) and an upper attachment fitting ( ) are interconnected through a vibration-isolating base ( ); a stopper fitting ( ) of a generally cylinder form partly cutout is connected to the main body fitting ( ) with its upper edge bent inwardly to form a stopper portion ( ), which is located above a stop flange ( ) of the upper attachment fitting ( ) and has a stopper function against a large vertical displacement; a stopper rubber member ( ) is fitted to the stopper fitting ( ) so as to extend from the upper surface of the stopper portion ( ) to an outer surface of its side plate by vulcanization molding; the cutout portion ( ) of the stopper fitting ( ) is plugged by a heat shield rubber membrane portion ( ) vulcanization molded integrally with the stopper rubber member ( ).

Antivibration device

In a vibration isolating mount having a toe correcting mechanism ( ) and installed with bored portions ( ) and an axial stopper ( ) in a rubber-like elastic body ( ) between an inner and an outer cylinder ( ) and ( ), as the stopper ( ), a portion of the outer cylinder on a side opposed to the toe correcting mechanism ( ) interposing the inner cylinder ( ) is extended in the axial direction and stopper rubber ( ) is arranged at a front end of the extended portion ( ) by which a rubber vulcanizing mold can be divided in an upper and a lower portion thereof even with the bored portion ( ), simplification of mold structure is achieved and light-weighted formation and durability of the mount are promoted.
