<p>A motor includes a shaft; a sleeve that supports the shaft rotatably; a housing including a cylindrical holding portion for holding an outer circumferential surface of the sleeve; a stator held against the cylindrical holding portion; and an attachment plate including an attachment portion held against the outer circumferential surface of the cylindrical holding portion. Herein, the cylindrical holding portion has a stator holding surface section facing the stator in a radial direction and an attachment plate holding surface section facing the attachment portion of the attachment plate in a radial direction. Further, the stator holding surface section has an outer diameter greater than that of the attachment plate holding surface section, and the inner circumferential surface of the cylindrical holding portion includes a surface region opposite to the stator holding surface section and another surface region opposite to the attachment plate holding surface section.</p> |
