Document Type and Number:
WIPO Patent Application WO/2024/070560
Kind Code:
A1
Abstract:
The present invention achieves a stable quality for a cylindrical anti-vibration device and intermediate sleeve by effectively applying a blast treatment, spray treatment, or the like for the intermediate sleeve to the entirety of the intermediate sleeve. In this cylindrical anti-vibration device 10, an inner shaft member 12 and an outer tube member 14 are coupled by a body rubber elastomer 16, and a cylindrical intermediate sleeve 18 extending in the circumferential direction between the inner shaft member 12 and the outer tube member 14 in the radial direction is adhered to the body rubber elastomer 16. A slit 22 penetrating in the axial direction is formed in a portion of the intermediate sleeve 18 in the circumferential direction, both end sections of the slit 22 are straight sections 24, 24 extending in the axial direction, and the direct overlap margin in the axial direction view of the straight sections 24, 24 on both sides is made smaller than the radial direction thickness dimension of the intermediate sleeve 18.
