Abstract: Provided is a liquid-filled vibration isolator through which durability of an elastic movable body can be improved. In a case that a liquid pressure of liquid passing through a second orifice P2 is exerted to an outer circumference portion 12 of an elastic movable body 10, whole of the outer circumference portion 12 deforms so as to bend. Based on deformation of the outer circumference portion 12, a first valve portion 13 and facing surfaces 81c, 91c mutually contact or separate. Thereby, the communication state and the blocking state of the second orifice P2 are switched. Since it can be restrained that stress is concentrated in a part of the outer circumference portion 12 by wholly bending the outer circumference portion 12, cracks are less likely to occur in the outer circumference portion 12.
