摘要： A sleeve supports a shaft. A housing member is arranged so as to surround the sleeve and make the end of the sleeve protrude. A base member holds the housing member and fixes a stator core so as to surround the housing member. A hub drives a recording disk by being rotated integrally with the shaft, with a magnet being fixed to an annular portion concentric with the shaft so as to face the stator core fixed to the base member. A thrust member is rotated integrally with the hub, and a descender portion and a ring portion.

摘要： In a disk drive device, a magnetic recording disk is mounted on a hub. A base rotatably supports the hub via a bearing unit. The base has a ring-shaped wall that surrounds the bearing unit and that protrudes towards the hub. A laminated core is fixed to the base. The laminated core has a ring portion and twelve teeth that radially outwardly extend from the ring portion. Coils are wound around the twelve teeth. The base includes an increasing-thickness portion formed so that the less the distance between a part of the increasing-thickness portion and the ring-shaped wall is, the thicker the part of the increasing-thickness portion becomes.

摘要： A rotating device includes: a rotating body, a fixed body and lubricant. A surrounding member in the fixed body has a sleeve and a housing for surrounding the sleeve. A first radial dynamic pressure generating groove and a second radial dynamic pressure generating groove are formed on at least one of the inner circumferential surface of the sleeve and the outer circumferential surface of a shaft in the rotating body. The sleeve has a flange portion protruding radially outward at the end portion of the sleeve near to a hub in the rotating body. A concave portion, which is made by axially concaving at least part of the area corresponding to a wall thickness of the sleeve on the inner circumference side of the flange portion, is circumferentially provided in the flange portion.

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.
