[Problem] To provide an antivibration device (10) capable of improving the durability of an antivibration base body (60) with spring constants made to differ in two directions orthogonal to an axis (O). [Solution] A junction (21) with an antivibration base body (60) joined to its outer periphery is equipped with a chamfer portion (22) where a corner connecting a flange portion (25) to the junction (21) is removed, a base portion (23) connected to the chamfer portion (22) in the axial direction, and an end portion (24) connected to the base portion (23) in the axial direction. At the base portion (23), a first projection plane made by being projected in a first direction (X) orthogonal to the axis (0) is substantially the same in area as a second projection plane made by being projected in a second direction orthogonal to the axis (O) and the first direction (X). At the end portion (24), the area of the second projection plane is set to be larger than the area of the first projection plane.
