Bearing unit and motor using the bearing unit

A motor comprising a bearing unit bearing a rotor rotatably relative to a stator,

• said bearing unit including:
• a radial bearing for bearing a shaft in the circumferential direction of the shaft;
• a first housing member provided on the outer periphery side and on one end side in the axial direction of said radial bearing and operative to retain said radial bearing;
• and
• a second housing member provided on the outer periphery side of said first housing member and on the other end side in the axial direction of said radial bearing, wherein
• said first and second housing members are united by a screw part provided on the outer periphery side of said first housing member and a screw part provided on the inner periphery side of said second housing member so as to sealingly contain said radial bearing, with a shaft passage hole provided on said one end side or said other end side in said axial direction so as to permit said shaft to pass therethrough, and
• the inside of said united first and second housing members is filled with a viscous fluid.
