  • Data storage medium support member, chucking device, brushless motor, and disc drive apparatus
    Patent number: 8281331
    Abstract: A data storage medium support member is produced by resin molding. The data storage medium support member includes an accommodating portion, a guide portion, and a gate cut portion. The accommodating portion accommodates a magnetic member around a central axis. The guide portion has a guide surface for guiding an inner edge of a disc, and is arranged radially outward of the accommodating portion. The gate cut portion is formed on a rear surface of the guide portion. The data storage medium support member can be produced by the resin molding while securing space for accommodating the magnetic member and preventing an increase in the axial dimension of the data storage medium support member.

  • MOTOR AND METHOD FOR MANUFACTURING THE MOTOR
    Publication number: 20080278027
    Abstract: A motor includes a shaft; a sleeve that supports the shaft rotatably; a housing including a cylindrical holding portion for holding an outer circumferential surface of the sleeve; a stator held against the cylindrical holding portion; and an attachment plate including an attachment portion held against the outer circumferential surface of the cylindrical holding portion. Herein, the cylindrical holding portion has a stator holding surface section facing the stator in a radial direction and an attachment plate holding surface section facing the attachment portion of the attachment plate in a radial direction. Further, the stator holding surface section has an outer diameter greater than that of the attachment plate holding surface section, and the inner circumferential surface of the cylindrical holding portion includes a surface region opposite to the stator holding surface section and another surface region opposite to the attachment plate holding surface section.
