PROBLEM TO BE SOLVED: To form an second orifice passage with fewer components in a simple structure, while the capacity for free tuning and sealing is sufficiently secured in a fluid filling-in vibration-resistant device having a balance chamber connected with a pressure received chamber through the first orifice passage and a sub- liquid chamber, respectively. SOLUTION: A fixing sleeve 68 firmly fixed on a rubber elastic plate 64 is externally fixed on a supporting projection 44 projecting into a partition member 36, and an approximately hat-shaped wall member 66 is externally fixed on the fixing sleeve 68. Further, the sub-liquid chamber 112 is formed between opposing faces of the wall member 66 and rubber elastic plate 64, and a second orifice passage 128 extending on an outer periphery of the fixing sleeve 68 to a peripheral direction is formed between opposing faces of a flanged portion 84 of the wall member 66 and partition member 36.
