Document Type and Number:
WIPO Patent Application WO/2011/093345
Kind Code:
A1
Abstract:
A protrusion (30) is formed so as to rise from a base plate (W), and the protrusion (30) is formed into a spacer (12) having predetermined outer diameter (D) and height (H). In forming the spacer (12), first the protrusion (30) is shaped to have a diameter greater than the predetermined outer diameter (D) and then shaped to have a height greater than the predetermined height (H). After that, the protrusion (30) is pressed and crushed to cause the top (30b) of the protrusion (30) to protrude outward in the radial direction and have a two-ply structure, and a through-hole (35) is formed in the top (30b). The configuration provides the top (30b) with strength provided by the double-layer structure. Also, a side section (30a) has high strength due to the pressing and compression. A member integrated with a sleeve is provided with the spacer (12), and the entire spacer (12) has sufficient strength.
