Claim:
1. A motor comprising: a stator that includes a stator core formed of a substantially ring-like yoke and teeth projecting in a radial inward direction from an inner circumference-side of the yoke, and a winding wound around the yoke in a radial direction via an insulator, the stator being formed of a molded resin body encapsulating the stator core, the insulator, and the winding; and a rotor including a rotor core and a motor rotating shaft inserted through a center of the rotor core, the rotor core being rotatably held in the inner circumference-side of the stator via an air gap, wherein projections are radially formed on an outer-circumferential surface of the molded resin body, each of the projections projecting in a radially outward direction from the outer-circumferential surface while extending in an axial direction and arranging a recess between circumferentially adjacent two projections; and the recesses are provided on portions that extend outward from a winding outer-circumference portion, said winding outer-circumference portion being portions of the winding that are located further toward an outer circumference-side in the radial direction than the stator core.
