    摘要: 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.
