摘要： In a rotating device, a housing includes a cylindrical outer surface facing an inner surface of a through hole and a guiding surface arranged on the underside of the outer surface, the diameter of the guiding surface being less than the diameter of the outer surface. Glue has an interface in an end space. In at least a part of the end space where the glue does not exist, conductive resin seamlessly is applied from the guiding surface to the inner surface of the through hole. With regard to a portion of the inner surface of the through hole that radially faces the guiding surface, the length, in the axial direction, of the portion that touches the conductive resin is greater than the length, in the axial direction, of the portion that touches the glue.

摘要： In a disk drive device, a recording disk is mounted on a rotor. A base has a bearing hole, the center of which is along the rotational axis of the rotor. A bearing unit rotatably supports the rotor with respect to the base, the bearing unit being glued to the bearing hole. A ring-shaped first groove, the center of which is along the rotational axis, is arranged on a side surface of the bearing hole. A ring-shaped second groove, the center of which is along the rotational axis, is arranged on an outer surface of the housing, the outer surface contacting the side surface of the bearing hole. The position of the second groove with respect to its direction along the rotational axis is different from the position of the first groove with respect to its direction along the rotational axis. The base and the bearing unit are electrically connected by a conductive resin applied along an edge portion of the bearing hole, the edge portion being on a lower surface of the base.
