摘要:
The rotating device includes a fixing body having a shaft and a shaft holder fixing the shaft, a rotating body having a shaft encircling member with a cylinder part encircling a shaft and a disk part, and a middle encircling member encircling the cylinder part and facing the disk part via a clearance in the direction of a rotational axis, a radial dynamic pressure generating groove disposed in either one of a surface of the cylinder part and a surface of the shaft facing with each other in the radial direction, a thrust dynamic pressure generating groove disposed in either one of a surface of the disk part and a surface of the shaft holder facing with each other in the rotational axis direction, and a lubricant continuously present from a first air-liquid interface to a second air-liquid interface between the rotating body and the fixing body.
