Abstract:
1. A vibration isolating device comprising: a first cylindrical fitting to be secured to a vehicle body side, a second fitting disposed upwardly of the first fitting along an axis center part of the first fitting and having a coupling member to be coupled to a vibration generator side, a rubber elastomer interposed between and interconnecting the first fitting and the second fitting, a front stopper rubber portion and a rear stopper rubber portion both having a mounted side attached to said coupling member of the second fitting or to a vibration generator to be fixed to the upside of the second fitting, said front and rear stopper rubber portions being separated from said first cylindrical fitting, a fore-and-aft stopper member disposed in front of and in back of and not connected to the front and rear stopper rubber portions, said fore-and-aft stopper member to be fixed to a vehicle body side, said front and rear stopper rubber portions respectively opposing portions of said fore-and-aft stopper member and defining gaps therebetween, said front and rear stopper rubber portions and the stopper member being relatively displaceable to close said gaps and engage one another to perform a stopper action in a fore-and-aft direction, at least one of said front and rear stopper rubber portions defining a cavity, said at least one of said front and rear stopper rubber portions having a tapered end portion for engaging said fore-and- falt stopper member, said tapered end portion having a tip and upper and lower inclined faces extending from said tip to face ends of said upper and lower inclined faces, said tip and said face ends defining a hypothetical tapered end triangular vertical cross section, and said cavity being disposed outside of said tapered end triangular vertical cross section and between said tapered end triangular vertical cross section and said mounted side of said at least one of said front and rear stopper rubber portions.
