PROBLEM TO BE SOLVED: To enhance production capability, and an yield to enjoy an advantage costs thereby. SOLUTION: A base 1 for a hard disk drive is integrally provided with burring 9 cylindrically projected in predetermined height on one side of the thickness direction of a panel 3 of a through hole 7 provided in the panel 3, and fixes a motor of the hard disk drive fitted in an inner periphery of the burring 9 to the burring 9 with an adhesive. Two circulting recessed parts 13, 15 are pressure formed by press on an inner peripheral surface 11 of the burring 9, a metal cutting process becomes unnecessary. precision management is easily performed, a failure such as corrosion is suppressed since no foundation appears, countermeasures such as deburring become unnecessary, and the production capability and the yield are enhanced to enjoy the advantage in costs.
