PROBLEM TO BE SOLVED: To provide a liquid filled vibration absorbing device whose movable plate is moved to suppress a change of a vibration absorbing device body into a high dynamic spring during the input of low frequency vibration, while suppressing the occurrence of abnormal noises due to the collision of the movable plate without causing the degradation of a vibration absorbing function due to flow path resistance in an orifice passage. SOLUTION: In the center of a partition member 16 which partitions an engine mount into a pressure receiving chamber 15a and a balancing chamber 15b, an intermediate chamber 20 is formed which movably stores the movable plate 100. The intermediate chamber 20 is communicated with the pressure receiving chamber 15a and the balancing chamber 15b via through-holes 18b, 19b. The movable plate 100 stored in the intermediate chamber 20 has a recessed portion 120 which is loosely inserted into the through-holes 18b, 19b with a space where liquid flows.
