Patent attributes
According to the present invention, there is provided a vibration damping device (10) including a first bracket (11) and a second bracket (12), a first attachment member (14), a second attachment member (15), and an elastic body (16). The second attachment member (15) includes an insertion cylinder portion (22) in which the second bracket (12) is inserted. The insertion cylinder portion (22) is provided with a stopper portion (56) which faces a stopper wall (55) provided in the first bracket (11), in a radial direction (Y) in a side wall portion (57) oriented outward in the radial direction (Y) of the insertion cylinder portion (22). The stopper portion (56) includes a first stopper portion (61) and a second stopper portion (62) which are disposed in a manner of being displaced in an axial direction (X) of the insertion cylinder portion (22). The first stopper portion (61) is constituted by a first elastic portion (58). The second stopper portion (62) includes a rigid member (25). A first distance (D1) between the first stopper portion (61) and the stopper wall (55) in the radial direction (Y) is equal to or shorter than a second distance (D2) between the second stopper portion (62) and the stopper wall (55) in the radial direction (Y).
