摘要： PROBLEM TO BE SOLVED: To put a brake without needing a special braking device and without affecting a fluid bearing surface.
SOLUTION: In this fluid bearing, a slide member 10 linearly moved while guided by a guide member 11, is supported by the fluid bearing surface 15. The guide member 11 projects downward from an opening portion formed on an lower surface of the slide member 10, and its side wall surface as a braking surface 12 is closely kept into contact with a braking surface 13 of the slide member 10. When the fluid of sufficient pressure is supplied to the fluid bearing surface 15, the slide member 10 is deformed as shown in Fig. 2(b), a clearance is formed between the braking surfaces 12, 13, and the slide member 10 is supported by the fluid bearing surface 15 in a non-contact state with the guide member, and allowed to be linearly movable. When the pressure of pressure fluid is lowered, the braking surfaces 12, 13 are closely kept into contact with each other as shown in Fig. 2(a), and the slide member 10 is braked. Thus the fluid bearing capable of being braked without needing the special braking device and damaging the bearing surface, can be provided.
