Abstract
In manufacturing a motor, a second protrusion of a lead bushing is inserted into a second through-hole in a bearing holder. A diameter increased portion on an upper end of the second protrusion fixes the lead bushing to the bearing holder. This configuration thus requires less dimensional accuracy as compared with a case where the lead bushing is press fitted to the bearing holder.
