Patent attributes
A vibration isolation device (10) includes a first mounting member (11) connected to one of a vibration generating portion and a vibration receiving portion, and a second mounting member (12) connected to the other; an elastic body (13) disposed between the mounting members (11, 12); a first stopper elastic body (27) having a first stopper surface (26) which is disposed on either one of opposing surfaces (24, 25) that oppose each other, respectively on the first mounting member (11) and the second mounting member (12), and which faces the other surface such as to be capable of coming into contact therewith; and a second stopper elastic body (29) having a second stopper surface (28) which is disposed on either one of the opposing surfaces (24, 25), respectively on the first mounting member (11) and the second mounting member (12), and which faces the other surface such as to be capable of coming into contact therewith. The distance between the first stopper surface (26) and the opposing surface (24) facing the first stopper surface (26) is smaller than the distance between the second stopper surface (28) and the opposing surface (24) facing the second stopper surface (28).
