Title:
VIBRATION-DAMPING DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/080310
Kind Code:
A1
Abstract:
In this vibration-damping device (1), positioned between an inner-side attachment member (11) and an outer tube (12) is a covering member (17) that, from the radially outer side, covers the space between a pair of moderately elastic bodies (32) circumferentially adjacent to each other and that, together with the inner-side attachment member, defines a pair of liquid chambers (14a, 14b). An orifice passage (19) that allows the pair of liquid chambers to communicate with each other is formed between the covering member and the outer tube. A first communication opening (18) and a second communication opening (20) that separately allow communication between the pair of liquid chambers and the orifice passage are formed in the covering member. An injection hole (12a) formed in the outer tube and sealed by a sealing material (16) is open toward at least one of the first communication opening and the second communication opening.
