Abstract: A bearing holder and a spindle motor having the same are disclosed. The bearing holder in accordance with an embodiment of the present invention can include a body, which has an insertion hole formed therein such that a bearing is inserted into the insertion hole, a first supporting protrusion, which is protruded downward from a bottom surface of the body along a circumference of the insertion hole, and a first bent indentation, which is formed on an inner circumferential surface of the first supporting protrusion such that the first supporting protrusion is bent toward an inner side. Thus, unnecessary deformation in the bearing holder can be prevented while the bearing holder is coupled to a base plate. Moreover, since the bearing holder forms an accurate positional relationship with respect to the base plate, noise and vibration can be prevented from occurring during the operation of the motor.

Abstract: In a spindle motor, a capillary seal portion having a radial dimension that decreases in an axially downward direction, and a labyrinth seal portion arranged above the capillary seal portion are defined between an outer circumferential surface of a rotating member and an inner circumferential surface of a tubular portion. The capillary seal portion includes a liquid surface of a lubricating oil positioned therewithin. The radial dimension of the labyrinth seal portion is smaller than the radial dimension of an upper end portion of the capillary seal portion, so that the labyrinth seal portion contributes to reducing evaporation of the lubricating oil.
