| 摘要 |
The present invention is an anti-vibration device (1) comprising a cylindrical first attachment member (2) that is connected to one of a vibration generating unit or a vibration receiving unit; a second attachment member (3) connected to the other; a first flexible member (4) flexibly connecting the first attachment member (2) and the second attachment member (3); a liquid chamber (5) containing liquid and provided in the first attachment member (2); a first partition wall (10) that divides the liquid chamber (5) in the axial direction and defines a sub liquid chamber (9) and a main liquid chamber (8) that uses as a part of its wall surface the first flexible member (4); a second partition wall (12) that divides the main liquid chamber (8) in the circumferential direction and defines a plurality of divided main liquid chambers (11); and a plurality of restricted flow paths (35) that connect the plurality of divided main liquid chambers (11A, 11B) and the sub liquid chamber (9). At least one portion of the first partition wall (10) is configured from an elastically deformable second flexible member (26), the second partition wall (12) is connected to the second attachment member (3) and the second flexible member (26), and the second flexible member (26) has a difference in rigidity in the radial direction. |
