发明名称 Bearing unit, and motor and electronic equipment, both equipped with the bearing unit
摘要 A bearing unit comprises a shaft, a radial bearing for supporting the shaft in a peripheral rotation direction of the shaft, a thrust bearing supporting an end of the shaft in a thrust direction of the shaft, a housing made of a molded body of a synthetic resin, inside of which housing the radial bearing and the thrust bearing are arranged, the housing having a sealed configuration except for a shaft insertion hole, through which the shaft is inserted, a slip-out preventing member provided on an end side of the radial bearing at which the thrust bearing is provided, the slip-out preventing member preventing the shaft from slipping out from the radial bearing, and a viscous fluid filled in the housing. The slip-out preventing member is made of a material having a thermal deformation temperature higher than a temperature applied to the slip-out preventing member upon molding of the housing.
