Abstract

A rotating apparatus includes a hub, a shaft housing portion having a center through-hole, a base plate, and a shaft with a cylindrical section housed in the through-hole. At a joint between the shaft housing portion and the hub is formed a bonding region for bonding the shaft housing portion and the hub by a hardening resin, and a narrow-gap region more toward the base plate than the bonding region. A gap between the shaft housing portion and the hub in the narrow-gap region is narrower than a gap between the shaft housing portion and the hub in the bonding region. The hub includes a fourth circumferential recessed portion recessed in the axial direction and a lower circumferential raised portion projecting in the axial direction on a radially inner side of the fourth circumferential recessed portion. The narrow-gap region is located inside the lower circumferential raised portion.
