Abstract:
A motor may include a bearing mechanism including a shaft arranged along a center axis, a sealing member has one-end closed cylindrical shape and a recess receiving a lower portion of the bearing mechanism, a stationary portion including a base defining a part of the housing, and a rotary portion rotating relative to the stationary portion about the center axis. The base has a through hole defined therein so as to have a center aligned with the center axis and pass through the base in an axial direction. The sealing member is fixed in a fixing region defined between an outer circumferential portion of the sealing member and an inner circumferential portion that defines the through hole in the base. The fixing region includes a sealing region where a clearance between the sealing member and the base is closed.
