Patent ID: 7946767

Claim:
A hydrostatic bearing configured to slide along a sliding surface of a structural body in a non-contact manner, the hydrostatic bearing comprising: a jetting part having a jetting surface configured to jet air onto the sliding surface; and a suction part having a suction surface configured to suction the air jetted from the jetting surface onto the sliding surface, wherein the jetting part includes a porous member having holes formed therein, a first external circumferential wall part disposed to contact and surround an external circumferential surface of the porous member to prevent leakage of the air from the external circumferential surface of the porous member, and an upper wall part including a contacting part that is in contact with an edge along an entire circumference of an upper surface of the porous member and forming a space for supplying the air to the porous member; wherein the suction part includes a second external circumferential wall part surrounding an external circumferential surface of the first external circumferential wall part, a suction space formed between the first external circumferential wall part and the second external circumferential wall part, and a suction surface formed between a lower edge of the second external circumferential wall part and the first external circumferential wall part and positioned higher than a lower end of the jetting part; wherein the first external circumferential wall part and the second external circumferential wall part are formed as separate parts.
