The housing includes a base portion substantially in a shape of a plate and arranged to extend radially below the rotating portion. The base portion includes a first lower surface arranged to face downward, and a through hole arranged to pass through the base portion in the vertical direction and arranged to have a portion of the bearing mechanism arranged therein. The sealing member is arranged to cover a lower side of the through hole, and includes at least a metal layer."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Spindle motor and disk drive apparatus","description":"A motor includes a rotating portion including a rotor magnet, and arranged to rotate about a central axis extending in a vertical direction; a bearing mechanism arranged to support the rotating portio","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9721608","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
