Claim Text:
1. A liquid-sealed anti-vibration device comprising: an inner tube; an outer tube; rubber bodies interconnecting the inner and outer tubes in a liquid-tight manner at two positions spaced in an axial direction; a partition wall disposed between the rubber bodies to divide a space between the inner and outer tubes into two chambers in the axial direction, the partition wall having an annular rigid member and an elastic member; said two chambers each being filled with non-compressible liquid; and a limiting passage provided in the partition wall to allow said two chambers to communicate with each other, wherein the limiting passage is formed by at least one passage groove, the passage groove being formed on a surface of the annular rigid member on a protruding side of the annular rigid member, and by a rigid tube member fixed to the elastic member so as to close a radial opening of the passage groove in a liquid-tight manner, and the rigid tube member for closing the radial opening of the passage groove of the limiting passage has one axial-end inward flange or one axial-end outward flange engaging with one axial-end surface edge section of the annular rigid member.
