The present invention aims at providing a liquid sealed type vibration isolator capable of positioning a partition excellently with the construction of the partition simplified, and maintaining stable damping characteristics of an orifice. To meet the requirements, an outer circumferential portion of the partition forming the orifice is made so that the outer circumferential portion defines at least a part of one or two sides of a cross section of the orifice, and a positioning device formed of a partition press fitting or inserting structure with respect to a groove, or a partition engaging structure is provided in a joint portion between the partition and the other orifice forming member with the construction of the partition simplified, whereby it is rendered possible to improve the accuracy of the partition and obtain a desired cross section of the orifice.
