Claims

[Scope of utility model registration request]

A base having one or more fluid supply ports, a fluid bearing provided inside the base and forming a fluid layer on an inner circumferential surface by fluid supplied from the fluid supply ports, and the fluid bearing A rotating body having a shaft portion rotatably supported by a bearing and a disk portion provided integrally with the shaft portion, and a fluid supplied to the center of the shaft portion of the rotating body through the fluid bearing. a fluid passage leading to the disc part; a substantially radial fluid distribution passage guiding the fluid guided from the fluid passage to the disc part toward the outer periphery of the disc part; a plurality of inclined nozzles that eject the ejected fluid in a substantially tangential direction of the disk portion and rotate the rotating body with the ejection force;
A truing device comprising: a grindstone provided on the rotating body for truing.
