  • Patent number: 9958024
    Abstract: In an elastic partition member, a movable diaphragm outer circumferential section for supporting an outer circumference of an elastic movable diaphragm is formed integral with a relief valve. The elastic movable diaphragm is integrally formed with the elastic movable diaphragm. An upward circular arc projection that extends upwardly is provided on an upper part of the movable diaphragm outer circumferential section, and is fixed by a fixing portion provided in an upper member of a partition. A portion in the vicinity of a base portion of the relief valve is formed as a rectilinear unsupported portion that is flush with the elastic movable diaphragm.

  • Patent number: 9878604
    Abstract: [Problem] To provide a liquid-sealed antivibration device capable of improving the position accuracy of an outer fitting member and a diaphragm. [Solution] Since a cylindrical outer fitting member 11 with an outer edge part of a diaphragm 10 connected thereto is externally fitted on a partition member 20 at an area on an inner peripheral surface of the outer fitting member 11 where the diaphragm 10 is not connected, that is, since the diaphragm 10 is not interposed between the partition member 20 and the outer fitting member 11, the position relation of the outer fitting member 11 to the partition member 20 can be stabilized, so that the outer fitting member 11 can be restrained from inclining relative to the partition member 20.

  • Patent number: 9855831
    Abstract: A liquid-sealed antivibration device capable of improving the position accuracy of an outer fitting member and a diaphragm. An outer fitting member (11) is externally fitted on a partition member (20) with an interposition portion (10b) interposed, and the interposition portion (10b) is made to be fixed in thickness. Thus, when a diameter reduction process is given to a second attaching member (3), the outer fitting member (11) is restrained from being displaced in a direction to slip out of the partition member (20). Therefore, the outer fitting member (11) is restrained from falling eccentric or inclined relative to the partition member (20), and hence, it can be realized that the outer fitting member (11) and the diaphragm (10) are improved in position accuracy.
