PURPOSE: A spindle motor is provided to reduce the application of load torque in a bearing by reducing the distance of force applied to the bearing. CONSTITUTION: A rotary shaft(140) includes a thrust plate(150) which is perpendicularly installed to the upper side. The thrust plate includes a thrust bearing. A bearing(120) supports the rotary shaft to be rotatably by receiving the rotary shaft. Protrusions with constant interval are formed on the upper center part of the bearing. The thrust plate is placed on the upper side of the protrusions. The bearing prevents the abrasion of a groove in a rotation state in order to reduce rotation load torque. The thrust plate includes a thrust bearing.
