Abstract
An easy-to-manufacture spindle motor has an aligning mechanism whose precision is equal to that of cutting of metallic materials without entailing an extra cost. The aligning mechanism is in contact with the center hole of a disk-shaped recording medium and comprises a turntable and an aligning member that has a sliding portion which can be slidably fitted into a guide portion disposed on the turntable. At least one of respective sliding faces of the guide portion disposed on the turntable and the aligning member is configured of a metallic component, and parts other than the metallic component or components of the turntable and/or aligning member are configured of resin materials.
