PROBLEM TO BE SOLVED: To inexpensively extend the length of an orifice. SOLUTION: In a liquid seal type vibration control device where a body hardware 12 and an upper side mounting fitting 14 are connected through a vibration-control base body 16, a diaphragm 18 is arranged in the body hardware 12 to form a liquid sealed chamber 20, and the liquid sealed chamber is divided into two, upper and lower chambers 20a, 20b communicated through an orifice 26 by a partition member 24, the first orifice 26a connected to the first liquid chamber 20a through an outer peripheral groove 41 of the partition member 24 is formed between the body hardware 12 and the first liquid chamber, and the inner circumferential end of a mounting fitting 38 arranged on the peripheral edge part of the diaphragm 18 is extended upward to about on the undersurface of the partition member 24. Thus, a space formed between the outer periphery of an extended part 38b and the partition member 24 is used as the second orifice 26b, and thus the total length of the orifice 26 is extended. |
