PROBLEM TO BE SOLVED: To provide a vibration-resistant device improving dimensional accuracy of a movable gap for an elastic film in a partitioning member. SOLUTION: In the vibration-resistant device, a first installing member 10 and second installing member 12 are combined together via a vibration-resistant base body 14, a fluid filling-in chamber 26 arranged between a diaphragm 22 and the vibration-resistant base body 14 is partitioned into two chambers by a partitioning member 30, and two chambers 26a and 26b are connected each other by an orifice 28. The partitioning member 30 is provided with an elastic film 32, and a first member 34 and a second member 36 restricting displacement of the elastic film. A recessed portion 44 housing the elastic film 32 is arranged on the first member 34, and a plane surface portion 36a connected with an end face 46 of an opening so as to block the opening of the recessed portion 44 is arranged on the second member 36. Thus, a gap 48 restricting the displacement of the elastic film 32 is formed between the first member 34 and second member 36. COPYRIGHT: (C)2004,JPO |
