    • PROBLEM TO BE SOLVED: To provide a dust-proof structure of a sleeve bearing, preventing oil contaminant from staying to reduce friction and noise due to rotation and further lengthen the use life of a motor by installing a sleeve bearing and a dust-proof cushion in the interior of a shaft tube and forming at least one oil return groove between the sleeve bearing and the dust-proof cushion. SOLUTION: This dust-proof structure is composed of the shaft tube, the sleeve bearing and the dust-proof cushion. The shaft tube can store the sleeve bearing and the dust-proof cushion. A shaft of the rotor is bored in a shaft hole of the sleeve bearing. The dust-proof cushion is provided on the upper side of the sleeve bearing, thereby preventing dust from being gathered in the sleeve bearing. At least one oil return groove is formed between the dust-proof cushion and the sleeve bearing, thereby heightening circulation and flowing of oil in the sleeve bearing, and keeping the lubrication between the sleeve bearing and the shaft.

    • PURPOSE:To produce a large effect of dynamic pressure by forcedly feeding the fluid which is sucked by the operation of a group of fins on a rotary table into grooves on the external periphery of a shaft member. CONSTITUTION:The air which is sucked from a suction passageway 14 is swirled by the revolution of a group of fins 20 which are formed on the lower face of a rotary table 2, and carried in the direction shown by the arrow. By the operation of the group of fins 20, the fluid is further forcedly sent from the slant part 7 of a funnel-shaped groove 8 and then discharged from an outlet passageway 18 via ?-shaped grooves 22 and 23 on the external periphery of a shaft member 4 and a vertical clearance 9. In other words, the fluid which is sucked from the suction passageway 14 is forced to travel in the direction as shown by the arrow inside the funnel-shaped groove 8 by the group of fins 20. During the further travel of the fluid, a dynamic pressure is produced at the rows 22 and 23 of the ?-shaped grooves which are cut on the external periphery of the shaft 4, and then runs in the direction shown by the arrow.
