Abstract:
A motor includes a bearing mechanism including a shaft disposed along a center axis extending in a lengthwise direction, a sealing member disposed on a lower side of the bearing mechanism, a stationary portion including a base constituting a part of the housing, and a rotary portion rotating relative to the stationary portion about the center axis via the bearing mechanism. 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 bearing mechanism is fixed to the base in a first fixing region defined between an inner circumferential portion of the base and an outer circumferential portion of the bearing mechanism. The sealing member is fixed to the base in a second fixing region defined between the inner circumferential portion of the base and an outer circumferential portion of the sealing member. At least one of the first fixing region and the second fixing region includes a sealing region.
