The first fixed body portion and the second fixed body portion are coupled at a coupling portion. The rotation body rotatably is assembled to the fixed body. The inhibiting structure is configured to inhibit foreign matter from entering the space through the coupling portion. The coupling portion is exposed to an outer surface of the fixed body.
