Claim 0:
1. A motor comprising:
a rotor rotatable about a center axis extending vertically;
a stator to rotate the rotor; 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 first opposing surface opposing the second housing in the axial direction; and
a first wall portion extending from the first opposing surface to the second side in the axial direction;

the second housing includes:
a second opposing surface opposing the first housing in the axial direction;
a second wall portion extending from the second opposing surface to the first side in the axial direction; and
a base portion holding the stator;

the first wall portion and the second wall portion oppose each other in a radial direction; the second housing further includes a third wall portion;
the first Wall portion includes:
an overlapping portion overlapping the third wall portion in the radial direction; and
a circumferential end portion protruding in a circumferential direction from the overlapping portion;

the circumferential end portion includes a protruding portion protruding to the radially outer side;
the protruding portion opposes an end surface of the third wall portion opposing the circumferential direction; and
the circumferential end portion is located at a different position in the circumferential direction than the third wall portion such that the circumferential end portion and the third wall portion do no overlap one another when viewed in the radial direction.
