Document Type and Number:
Japanese Patent JPH1061583
Kind Code:

Abstract:
To drastically reduce manufacturing cost by forming supporting bodies for supporting a bearing ball and a bearing cap by drawing of stainless steel, and to reduce the weight by thinning the wall.
A bearing ball 28 is pressed in the upper end of a ball supporting body 32. This ball supporting body 32 is formed by drawing a raw plate of stainless steel. A rotor 20 is rotatably arranged above the bearing ball 28 through a bearing cap 30.
