PULLING PLATE FOR SPINDLE MOTOR AND SPINDLE MOTOR HAVING THE SAME

摘要

PURPOSE: A spindle motor and a pulling plate for the spindle motor are provided to install the pulling plate in a base member by deformation of a plastic deformation unit, thereby improving combination intensity between the pulling plate and the base member. CONSTITUTION: A circular pulling plate(150) is settled in an insertion groove(114) of a base member(110). A jig deforms a plastic deformation unit(154) of the pulling plate corresponding to a descent of the jig. An extension unit(154) is moved to the outside of a radial direction and is touched to a side wall(114a) of the insertion groove. The pulling plate is installed in the insertion groove of the base member by deformation of the plastic deformation unit.
