Claims

[Scope of utility model registration request]

An electrorheological liquid whose viscosity changes depending on the applied electric field strength is sealed in a sealed chamber that deforms due to vibration input, and the sealed chamber is partitioned by a partition wall with a constricted flow path to form a pair of liquid chambers. None, in a liquid-filled anti-vibration mount in which an electrode for applying an electric field to the electrorheological liquid flowing through the flow path wall of the throttle flow path is provided, the partition walls are opposed to each other at a predetermined interval. Consisting of a pair of partition plates with the above-mentioned throttle channel between the faces, a plurality of liquid flow ports communicating with the throttle channel are opened on the plate surface of one partition plate, and a plurality of liquid flow ports are opened on the plate surface of the other partition plate. , at a position offset from the liquid flow port of one of the partition plates in plan view,
A plurality of liquid flow ports communicating with the throttle flow path are opened, and the electrodes are provided on opposing surfaces of both the partition plates at least in a portion connecting the liquid flow ports with each other in a plan view. Enclosed anti-vibration mount.
