ABSTRACT:
A foil bearing is provided, which is simple in structure, has a large load capacity and a large damping capability and can therefore allow a rotary shaft having a large unbalance as compared with the conventional bearing to be driven stably at a high speed. A spindle device utilizing such foil bearing is also provided, which is designed to increase the permissible amount of unbalance and also to have a light-weight feature. Each of the foil bearings504and505includes an elastic member2prepared from a wire net formed by braiding wires, and a thin bearing foil3supported by the elastic member2and defining an elastic bearing surface S. The respective foil bearing504and505is used at least as a radial bearing504in the spindle device including a rotary shaft4having a head mount501a,on which an atomizer head is mounted, and the radial and thrust bearings504and505for rotatably supporting the rotary shaft4.
