| description | To provide a base plate which can reduce leakage of gas filled inside a housing, a motor using the base plate, a disk drive device and a manufacturing method of the base plate.SOLUTION: A base plate 41 is a part of a housing of a disk drive device having a disk rotating with a rotation axis as a center and is a cast product. The base plate has a bottom plate part 411 and a peripheral wall part 412. The bottom plate part is rectangular when viewed from an axial direction. The peripheral wall part extends in one side in the axial direction from an outer peripheral edge of the bottom plate part and surrounds a periphery of the bottom plate part. During casting of the base plate, a metal member 415 is inserted into a thick part 412a and the metal member is buried in a part of the peripheral wall part. The metal member is formed of a member different from a casting member constituting the peripheral wall part.SELECTED DRAWING: Figure 2
【課題】筐体の内部に充填されたガスの漏洩を低減できるベースプレート、それを用いたモータ、ディスク駆動装置及びベースプレートの製造方法を提供する。【解決手段】ベースプレート４１は、回転軸を中心に回転するディスクを有するディスク駆動装置の筐体の一部であり、鋳造品である。ベースプレートは、底板部４１１と、周壁部４１２と、を有する。底板部は、軸方向から見て矩形状である。周壁部は、底板部の外周縁から軸方向一方側に延びて底板部の周囲を囲む。ベースプレートの鋳造時に、金属部材４１５が、厚肉部４１２ａにインサートされており、周壁部の一部には、金属部材が埋設されている。金属部材は、周壁部を構成する鋳造部材とは別部材から成る。【選択図】図２ |
