To provide a technology that makes it possible to improve sealability of a base while avoiding occurrences of blow holes in a pivot shaft.SOLUTION: A base 10 is a part of a housing of a hard disk drive. The base 10 includes a bottom plate portion 12, a pivot shaft 14, and a first adhesive 16. The bottom plate portion 12 includes a bottom plate upper surface 12a facing upward, a bottom plate lower surface 12b facing downward, and a through hole 12c extending from the bottom plate upper surface 12a toward the bottom plate lower surface 12b. The pivot shaft 14 includes a base outer surface 14a1 press-fitted into an inner surface 12c1 of the through hole facing inward in the through hole 12c. The first adhesive 16 is interposed between the inner surface 12c1 of the through hole and the base outer surface 14a1.SELECTED DRAWING: Figure 3 【課題】ピボット用シャフトにおける鋳巣の発生を回避しつつ、ベースの密封性向上を可能にする技術を提供する。【解決手段】ベース１０は、ハードディスク駆動装置の筐体の一部となる。ベース１０は、底板部１２と、ピボット用シャフト１４と、第１接着剤１６と、を備える。底板部１２は、上方を向く底板上面１２ａと、下方を向く底板下面１２ｂと、底板上面１２ａから底板下面１２ｂに向かって延在する貫通孔１２ｃと、を有する。ピボット用シャフト１４は、貫通孔１２ｃにおいて内方を向く貫通孔内面１２ｃ１に圧入される基部外面１４ａ１を有する。第１接着剤１６は、貫通孔内面１２ｃ１と基部外面１４ａ１との間に介在する。【選択図】図３
