Title:
FIXING MEMBER FOR DUST COVER
Document Type and Number:
WIPO Patent Application WO/2007/138995
Kind Code:
A1
Abstract:
An annular fixing member embedded in a dust cover in order to fix it to its mounting
portion. The fixing member integrally has an annular base part and bore teeth
of a circular conical surface shape. The bore teeth are provided at the bore edge
of the annular base part and determine the margin of fitting of the fixing member
to a mounting portion. In mounting the dust cover on the mounting portion, the
fixing member minimizes possibility of the entire dust cover from being mounted
tilted to thereby realize accurate mounting of the dust cover. To achieve this,
the thickness of the bore teeth is set less than the thickness of the annular base
part. As a result, the annular base part is less likely to be deformed by following
the deformation of the bore teeth when the bore teeth are deformed in mounting
and fixing of the dust cover. Alternatively, a thin wall part is formed at the
root of the bore teeth, and this results that, when the bore teeth is deformed in
mounting and fixing of the dust cover, the annular base part is less likely to be
deformed by following the deformation of the bore teeth.
