Abstract
A rotating apparatus includes a hub, a shaft housing portion having a center through-hole, and a base plate, having a base circular part that extends axially and with an inner surface thereof used as a bearing hole. Further included is a shaft with a cylindrical section housed in the through-hole, an extending section formed integrally with the cylindrical section and extending radially from a first end of the cylindrical section, and an annular section provided radially from a second end of the cylindrical section. Provided on the inner surface of the through-hole is a groove configured to generate radial dynamic pressure in lubricant. The rotatable rotor includes a portion encircling at least part of the annular section. An opening of the bearing hole surrounds a part of the shaft housing portion, the extending section inserted and fixed into the opening, with a hardening resin interposed therebetween.
