Abstract
A rotating device includes a retained assembly including a spherical retained member with a spherical encircled face, and an encircling member that includes an annular end face which encircles the spherical retained member and which extends outwardly in a radial direction, a retainer assembly including a retainer member which includes an encircling face encircling the encircled face and which retains thereinside a part of the spherical retained member, and a facing member that faces the encircling member in an axial direction, the retainer assembly supporting the retained assembly in a freely and relatively rotatable manner, and forming a fluid dynamic bearing mechanism, and a thrust dynamic pressure generating groove formed in at least either one of a surface of the encircling member and a surface of the facing member, which surfaces face with each other in the axial direction.
