Disclosed herein is a base for a hard disk drive, including: a base plate; and a double bent part doubly bent from an outer edge of the base plate, wherein a thickness of a plate material forming the double bent part is thinner than that of a plate material forming the base plate. The plate material of the base plate including a central portion of the base and the plate material of the double bent part formed at an outer side of the base have a relative difference in a thickness therebetween, thereby making it possible to secure rigidity at both of the central portion of the base and the outer side of the base. |
