Abstract

A motor able to prevent axial displacement of a rotor in a simple structure without increasing the number of parts of the motor. The motor includes a rotor including a shaft, a housing configured to support the shaft rotatably and movably in a limited manner in an axial direction, a flange disposed on an axially outside of the housing and configured to rotate integrally with the shaft, the flange projecting radially outward from the shaft and being configured to prevent a foreign object from entering the housing, and a temporary tacking structure provided in at least one of the flange and the housing, and configured to temporarily tack the housing and the flange to each other in the axial direction.
