1. A motor comprising:
a rotor that is rotatable about a rotation axis;
a stator that opposes the rotor with a gap interposed radially inward;
a stator accommodating portion in a tubular shape that accommodates the stator and includes an opening on one end surface in an axial direction;
a seal filled in the stator accommodating portion; and
a lid above the stator that covers the opening; wherein
the stator accommodating portion includes:
a cutout recessed from one end in the axial direction to another side in the axial direction and from which a lead wire electrically connected to the stator is pulled out to a radially outer position; and
a pullout piece that protrudes radially outward from a bottom of the cutout and on which the lead wire is provided;
the pullout piece includes a pullout inclined portion;
the pullout inclined portion is inclined in the one end in the axial direction and extends radially outward from the bottom of the cutout;
the lead wire is positioned between the lid and the pullout piece via an elastic portion located on an end surface on one side in the axial direction of the pullout piece; and
an upper end of the elastic portion in the axial direction is located above an upper end of the seal in the axial direction, the lead wire is provided directly on the upper end of the elastic portion.
