Title:
VIBRATION ISOLATING DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/131508
Kind Code:
A1
Abstract:
[Problem] To provide a vibration isolating device in which it is possible to improve the durability of a vibration isolating base body. [Solution] In an elastically deformable portion 33, a circumferential direction cross-sectional area, which is a cross-sectional area in a cross section sectioned continuously in a circumferential direction along an axis O direction, is substantially constant at each position in a radial direction. By this means, an axis O direction dimension of the elastically deformable portion 33 can be made to decrease gradually with increasing distance from the axis O in the radial direction, and both end surfaces, in the axis O direction, of the elastically deformable portion 33 can be formed into a smooth curved surface from the radially inner side to the radially outer side. The elastically deformable portion 33 can therefore be connected smoothly to a second membrane portion, and therefore, if the elastically deformable portion 33 is deformed in such a way as to be compressed or pulled in the radial direction, it is possible to suppress the concentration of strain in a relatively thin part on the radially outer side of the elastically deformable portion 33. The durability of a vibration isolating base body 30 can therefore be improved.
