1. A motor, comprising:
a rotor rotatable in a circumferential direction around a center axis extending vertically;
a stator to rotate the rotor;
a lead wire electrically connected to the stator; and
a housing covering the rotor and the stator from a radially outer side; wherein
the housing includes;
a first housing located on a first side in an axial direction; and
a second housing located on a second side in the axial direction;
the first housing includes a wiring convex portion protruding toward the second side in the axial direction;
the second housing includes a wiring recess that is recessed toward the second side in the axial direction and penetrates in a radial direction;
the wiring convex portion is located in the wiring recess;
the wiring convex portion includes a tip surface opposing the second side in the axial direction;
the wiring recess includes a bottom surface opposing the first side in the axial direction;
the lead wire is located between the tip surface and the bottom surface as viewed in the radial direction;
at least a portion of the tip surface is located at a position shifted in the radial direction from a position opposing the bottom surface in the axial direction;
the wiring convex portion includes:
a first outer surface opposing a first side in the circumferential direction; and
a second outer surface opposing a second side in the circumferential direction;
the first outer surface includes an inclined surface that is inclined toward the second side in the circumferential direction toward the second side in the axial direction; and
the second outer surface is a surface parallel or substantially parallel to the axial direction.
