MOTOR AND DISK DRIVING DEVICE EQUIPPED WITH MOTOR

摘要

PURPOSE: A motor with a strength reinforcement unit and disk storage drive device mounted to the same are provided to increase rigidity and realize slimness by widening a contact surface of a base plate which is contacted to a lower surface of an axial direction and the lower surface of the axial direction of a sleeve housing. CONSTITUTION: A sleeve housing(70) includes an inside diameter, a core receiver expanded from the inside diameter to an outside of a direction of external diameter, and an outer diameter unit expanded from the core receiver to a lower part of an axial direction. A sleeve(52) supporting a shaft(50) is pressed inside the diameter. A base plate(60) includes a strength reinforcing unit(62) which is contacted to at least one part of the inside surface of the core receiver and the outer diameter unit. A stopper ring fixes a lower part of a shaft projected from a lower part of an axial direction of the sleeve and prevents shaft from dropping out.
