Liquid-filled vibration damping device

A liquid-filled vibration damping device comprising:

• a first attachment member and a second attachment member that are vertically remote from each other and are elastically connected by a main rubber elastic body;
• and
• a closure member overlapped on and attached to the second attachment member from below with a seal member interposed therebetween to define and seal a liquid chamber;
• wherein
• the second attachment member and the closure member are attached to each other by a plurality of connecting locks arranged in a circumferential direction;
• each of the plurality of connecting locks includes:
• a flexible locking piece projecting from one toward another of the second attachment member and the closure member, the flexible locking piece being elastically deformable radially outward and having at least one locking hole, and
• a locking claw formed on the other of the second attachment member and the closure member and hooked to the locking hole of the flexible locking piece;
• the flexible locking piece is provided with a guide groove extending linearly from the locking hole in a direction of projection to guide the locking claw into the locking hole;
• and
• the locking claw has a tapered projecting shape whose width dimension is made smaller at a distal end than at a proximal end in a direction of projection.
