Summary:PROBLEM TO BE SOLVED: To provide a liquid-sealed vibration damping device which can suppress the lowering of vibration damping performance even if a stopper member is arranged.SOLUTION: A first liquid chamber LR1 and a second liquid chamber LR2 are defined by an elastic member 40 connected to an inner cylinder member 30, and an outer cylinder member 20, and liquid 60 is filled therein. An arm part is connected to a side intersecting with a paper face at a main body part 42 which contacts with the inner cylinder member 30 out of the elastic member 40, and the arm part is connected to the outer cylinder member 20. In the main body part 42, stopper members 50 which protrude from the main body part 42 are formed at both sides in a diameter radial direction DR. Grooves Di are formed at the stopper members 50.SELECTED DRAWING: Figure 2 【課題】ストッパ部材を設ける場合であっても、制振性能の低下を抑制できるようにした液体封入式制振装置を提供する。【解決手段】内筒部材３０に連結された弾性部材４０と外筒部材２０とによって、第１液室ＬＲ１および第２液室ＬＲ２が区画され、液体６０が充填されている。弾性部材４０のうち内筒部材３０に接触している本体部４２における紙面に直交する側には、腕部が結合されており、腕部は外筒部材２０に結合されている。本体部４２には、直交径方向ＤＲの両側において、本体部４２から突出するストッパ部材５０が形成されている。ストッパ部材５０には、溝Ｄｉが形成されている。【選択図】図２
