Abstract: A vibration-absorbing engine mounting device with fluid damping which comprises: an upper mounting member, a lower mounting member, a rubber wall body interposed between both the mounting members with its upper and lower portions being air-tightly bonded to the upper and lower mounting members, respectively, a block damper transversely provided in the rubber wall body, and a capsule encased in a space enclosed by the former four members, thus defining a closed chamber enclosed by the former five members. The capsule comprises an exterior rigid case, an interior sealed bag encapsulated in the rigid case, defining a sacciform chamber and an orifice member entering the former two. The closed chamber and the sacciform chamber are filled with fluid, whereby they are put in communication with one another by the passage of fluid via the orifice member.
