Claim Text:
1. An inverted liquid sealed mount comprising: an inner member being mounted on one of a vibration source side member and a vibration receiving side member; an outer member surrounding the inner member and being mounted on the other of the vibration source side member and the vibration receiving side member; an insulator of a circular truncated cone shape covering an opening section of one end of the outer member and elastically connecting the inner member and the outer member; a liquid chamber being formed between the insulator and a diaphragm which covers an opening section of the other end of the outer member; a partition member separating the liquid chamber into a primary liquid chamber and a secondary liquid chamber; an orifice communicating between the primary liquid chamber and the secondary liquid chamber; and a top of the insulator projecting into the primary liquid chamber in an input direction of vibration which pressurizes the primary liquid chamber; wherein resistors are arranged in an annular recess section formed around the insulator within the primary liquid chamber and narrows a portion of the annular recess section so as to form a regulation gap, and the resistors are mounted by engagement with elastic support sections provided within the primary liquid chamber, the resistors and the elastic support sections are detachably engaged by an interference fit between engaging projections and engaging recesses as relatively movable, and wherein one of the engaging projections and the engaging recesses are provided on the resistors while the other is provided on the elastic support section formed within the primary liquid chamber, the engaging recesses are provided with vertical grooves extending in the upward and downward direction and fitted by insertion with engaging projections, the resistors are formed separate from the insulator and the partition member and arranged partially in the circumferential direction of the annular recesses, the regulation gap is provided partially in the liquid channel in the circumferential direction of the annular recess section by the resistors, and the regulation gap is changed and fluid resonance in the annular recess is controlled by changing the resistors.
