Abstract
A motor includes a stator unit and a rotor rotatable relative to the stator unit. The stator unit includes a stator, a resin portion, a support portion, and an annular recess. The stator includes a stator core, an insulator, and a conducting wire wound around the stator core with the insulator interposed therebetween. The resin portion covers at least part of the stator. The support portion supports the stator. At an end portion of the stator unit on one side in an axial direction, the recess is recessed toward another side in the axial direction. The resin portion is positioned further in a radially outer direction than the recess. The rotor includes an annular projection extending toward the other side in the axial direction. At least part of the projection is accommodated in the recess.
