Document Type and Number:
WIPO Patent Application WO/2014/192548
Kind Code:
A1
Abstract:
The purpose of the present invention is to enable: minimisation of distortion in a membrane section of a dust cover by the membrane section being an hourglass shape, even if reinforcing rings are embedded in a large diameter opening end section, and a small diameter opening other-end section of the dust cover; and provision of functional superiority, and superiority with regard to assembly by suppressing a reduction in the durability of the dust cover. Therefore, the present invention comprises a ball joint dust cover made from an elastic material, wherein: a spherical head section formed at one end of a ball stud is held inside a socket; a shaft at the other end of the ball stud is fixed, by being clamped, to a knuckle; a large diameter opening end section, in which a reinforcing ring is embedded, is held fixed on the outer peripheral surface of the socket; a small diameter opening other-end section, in which a reinforcing ring is embedded, is held on the shaft; and a membrane section couples the large diameter opening section, and the small diameter opening section. The dust cover is configured such that the maximum inner diameter of the membrane section is larger than the inner diameter of the reinforcing ring embedded in the large diameter opening end section.
