Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a liquid sealed vibration absorbing device wherein liquid pressure in a main liquid chamber is lower during the input of great-amplitude vibration. SOLUTION: An orifice board 31 has a rising wall portion 31d partitioning an orifice passage 34 from a movable plate recessed portion 31c. The rising wall portion 31d has an opening portion 31i communicating the orifice passage 34 with the movable plate recessed portion 31c. On the outer peripheral face of a movable plate 35 at its site corresponding to the opening portion 35i, a protruded portion 35a is formed which is fitted into the opening portion 35i while extending to the radial outside of a cylinder.
