Title:
VIBRATION-DAMPING DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/095724
Kind Code:
A1
Abstract:
An outer-side attachment member (111) is provided with a first end member (117), a second end member (118), and an intermediate member (116). The first end member (117) and the second end member (118) are fitted into respective opposing ends in the axial direction of the intermediate member (116). On either one of opposing end surfaces in the axial direction of a first mount projection (124) provided to the intermediate member (116), a connection counterpart (135) is disposed, the connection counterpart being provided to either a vibration generation part or a vibration receiving part. On the other end surface, a second mount projection (125) is disposed. The first mount projection (124) and the second mount projection (125) each have an insertion hole (111a) having inserted therethrough a fixing bolt (136) for integrally fixing the first mount projection (124) and the second mount projection (125) and for connecting the first mount projection (124) to the connection counterpart (135). At opposing ends in the axial direction of the intermediate member (116), a first crimp part (128) and a second crimp part (129) are formed for respectively crimping the first end member (117) and the second end member (118). The circumferential length of the first crimp part (128) is longer than that of the second crimp part (129).
