Abstract
The invention is a liquid filled type vibration isolating device () which includes a partition member () that partitions a liquid chamber () within a first attachment member () filled with a liquid into a first liquid chamber () and a second liquid chamber (), and in which a restricted passage (), which is configured to allow the first liquid chamber and the second liquid chamber to communicate with each other, is formed in the partition member. The restricted passage includes a first communication part () opening to the first liquid chamber, a second communication part opening to the second liquid chamber, and a main flow passage () that allows the first communication part and the second communication part to communicate with each other. At least one of the first communication part and the second communication part includes a plurality of pores () that penetrate a first barrier () facing the first liquid chamber or the second liquid chamber. At least one pore of the plurality of pores has a flow passage length of the pore that is 3 times or more the minimum value of the internal diameter of the pore.
