Abstract

The present invention provides a liquid-sealed vibration damping device that improves the accuracy and stability of the alignment of the two components in a simple assembly structure having a sealing property based on the connection locking part of the second mounting component and the sealing component. In this liquid-sealed vibration damping device (12), the connection locking part (94) assembled by overlapping the second mounting component (22) and the sealing component (30) in the vertical direction is configured to include a flexible locking piece (98) and a locking claw (96) hooking into the locking hole (100) of the locking piece (98). A guide groove (112) is formed in the locking piece (98) that extends linearly from the locking hole (100) in the protruding direction and guides the locking claw (96) into the locking hole (100).
