Abstract
A apparatus is provided in which, in a state before being assembled to a drive target, one end of a rotating shaft is not supported by a bearing, and in this state, the rotating shaft is pressed to the side of a bracket by coil springs and thus centering of the rotating shaft is maintained. In this way, axial run-out of the rotating shaft before a magnetic motor is assembled to the drive target is inhibited. Thus, damage and deterioration in assembly efficiency as a result of axial run-out of the rotating shaft can be inhibited, such as deterioration in assembly efficiency caused by adhesion between a magnet and coils wound on an armature core, for example.
