<P>PROBLEM TO BE SOLVED: To provide a liquid sealing type vibration control device that can improve the durability of an elastic wall. <P>SOLUTION: A partition 34 separating a primary liquid chamber 36 from an auxiliary liquid chamber 38 is constituted by an annular orifice formation member 42, an elastic wall 44 which plugs the hollow part of the foregoing member, and a pair of partition plates 46, 48 which are connected with each other to sandwich the elastic wall via a connection part 56 penetrating through the elastic wall. The outer diameter D1 of the partition plate 46 to the primary liquid chamber side is set to be greater than the inner diameter D2 at the axial end face 42B of the orifice formation member 42 (D1>D2) so that the outermost peripheral edge 46A of the partition plate 46 to the primary chamber side is positioned at a radially outer location Ko being more radially outside than the inner peripheral edge 42B1 of the axial end face 42B at an axially outer location Xo with respect to the axial end face 42B to the primary liquid chamber side of the orifice formation member 42. <P>COPYRIGHT: (C)2013,JPO&INPIT |
