    摘要: A dynamic bearing device includes: a housing; a bearing sleeve arranged inside the housing; a shaft member rotating relative to the housing and the bearing sleeve; and a radial bearing portion supporting the shaft member radially in a non-contact manner by a dynamic pressure action of a lubricant generated in a radial bearing clearance. The housing is formed of a leadless brass whose Sn content is regulated to 0.01 wt % or less.
