Bearing unit, motor using the bearing unit, and electronic equipment using the motor

A motor having a rotor, a stator, and a bearing unit for rotatably supporting said rotor to said stator, wherein said bearing unit comprises:

• a shaft;
• a radial bearing which supports an outer circumferential surface of said shaft and which has an upper end surface and a lower end surface;
• a housing for accommodating said radial bearing, said housing having an open end from which said shaft is inserted and a closed end opposite to said open end in the axial direction of said shaft;
• a lubricating oil filled in said housing to reduce rotational friction of said shaft;
• a holding member provided at said open end of said housing which holds said lubricating oil and which has an upper surface and a lower surface;
• and
• a sealing member for closing said open end of said housing to prevent leakage of said lubricating
• wherein,
• said sealing member has a side wall portion interposed between said holding member and said shaft and opposed to the outer circumferential surface of said shaft, and
• the lower surface of the holding member is in contact with the upper end surface of the radial bearing.
