Abstract:
A hub includes first and second side surfaces respectively opposed to inner and outer circumferential surfaces of an upper portion of a magnetic member, and a ceiling surface arranged to interconnect an upper ends of the first and second side surfaces. The adhesive agent is interposed between the inner circumferential surface of the upper portion of the magnetic member and the first side surface of the hub and between the upper surface of the magnetic member and the ceiling surface of the hub. Radial distance between the inner circumferential surface of the upper portion of the magnetic member and the first side surface of the hub and axial distance between the upper surface of the magnetic member and the ceiling surface of the hub are smaller than radial distance between the outer circumferential surface of the upper portion of the magnetic member and the second side surface of the hub.
