摘要：A spindle motor includes a bracket, a shaft member fixed to the bracket, a hub member rotatably mounted on the shaft member with a bearing member therebetween, a rotor magnet mounted on the hub member, a stator disposed in opposed relation to the rotor magnet, and a magnetic fluid sealing assembly disposed on on outer side of the bearings. The shaft member has an elastic sealing member which seals a through-hole formed in the shaft.
