PURPOSE: A bearing with a permanent magnet, which reduces the noise or the frictional heat which are generated by the rotation of the bearing, is provided to prevent the contact of a shaft and a housing by the repulsion of a bearing. CONSTITUTION: A bearing with a permanent magnet comprises a housing magnet member and a shaft magnet member(10). The housing magnet member has the cylindrical arranged within the housing. The shaft magnet member has cylindrical and is arranged on shaft. The shaft magnet member comprises a magnet device(11) and elastic member(12). The magnet device is arranged along the columnar direction of the shaft magnet member. The elastic member has the force of restitution to the each other distant direction combined in both ends. |
