    摘要: A spindle motor includes a shaft arranged in an upward/downward direction along a central axis; a base member including a substantially cylindrical holder portion arranged around the central axis; a bearing unit arranged radially inward of the holder portion; and a rotating portion arranged above the base member to rotate about the central axis. The rotating portion preferably includes a mounting surface on which a disk is to be mounted. An adhesive containing an electrically conductive material and an adhesive containing an externally stimulated curing material and/or an anaerobic curing material are arranged in a clearance space defined between an inner circumferential surface of the holder portion and an outer circumferential surface of the bearing unit. The adhesive containing the electrically conductive material is arranged above the adhesive containing the externally stimulated curing material and/or the anaerobic curing material.

    摘要: A spindle motor includes a stationary portion and a rotating portion including a seal defining portion. The stationary portion includes a shaft portion, an annular member fixed to an upper portion of the shaft portion in, for example, a tight-fitting condition, and a cap member. A radially inner end portion of the cap member is fixed to each of the shaft portion and the annular member preferably through, for example, an adhesive. An upper seal portion, in which a surface of a lubricating oil is arranged, is defined in an upper seal gap defined between an outer circumferential surface of the annular member and an inner circumferential surface of the seal defining portion. The cap member is arranged to cover an upper side of the upper seal portion.
