Document Type and Number:
WIPO Patent Application WO/2018/070505
Kind Code:
A1
Abstract:
The present invention suitably suppresses damage to a flange part and an outer cylinder when the flange part and the outer cylinder are assembled to an attachment member. A vibration-damping device (10) comprises an inner cylinder (11), a resin outer cylinder (12) that is disposed radially outward of the inner cylinder (11), and a rubber elastic body (13) that connects the inner cylinder (11) and the outer cylinder (12). The outer cylinder (12) comprises a press-fit part (14) that is press-fitted into an insertion hole (51) formed in an attachment member (50). The press-fit part (14) of the outer cylinder (12) comprises a flange part (17) that protrudes radially outward from an end part that is in the opposite direction from the direction in which the press-fitting into the attachment member (50) occurs. The boundary (20) between the flange part (17) and the end part of the press-fit part (14) is reinforced from axially outward of the press-fit part (14) by a reinforcing part (19).
