Abstract:
PROBLEM TO BE SOLVED: To simplify a structure and facilitate manufacturing while securing a product characteristic.SOLUTION: A vibration-proof device includes: a cylindrical first mounting member connected to one of a vibration generation section and a vibration reception section; a second mounting member connected to the other; an elastic body for connecting both of the mounting members; and a partition member 16 for partitioning a liquid chamber in the first mounting member in which liquid L is sealed into a first liquid chamber 14 and a second liquid chamber 15. At least one of the first liquid chamber 14 and the second liquid chamber 15 has the elastic body on a part of a wall surface. The partition member 16 includes a communication passage 30 for communicating the first liquid chamber 14 with the second liquid chamber 15. The communication passage 30 includes a branch section 33 for branching a flow of the liquid L flowing through the communication passage 30 and a confluence section 32 for making at least a part of the flow of the liquid L branched by the branch section 33 confluent with a flow of another liquid L flowing in the communication passage 30, between the first liquid chamber 14 and the second liquid chamber 15.
